I didn't find a real solution. Mathworks created some wrapper tool. But this will only output the results after matlab has exited. You won't get any ouput during execution.

Depending what you are doing with Matlab you could probably launch it in command line without GUI. I used this on a server and it behaves pretty much like a shell script and writes to standards outputs.

See the <a href="http://www.mathworks.fr/help/techdoc/matlab_env/f8-4994.html" rel="nofollow">startup options</a>.

I used the following:

<pre><code>/path/to/matlab -nojvm -nodisplay -nosplash -nodesktop -r /path/to/mfile

EDIT: forgot to mention one very important little detail, place an <code>exit</code> command at the end of your mfile or Matlab will hang there waiting.

blocks|key|81427|text|在MATLAB中似乎没有任何好的方法来做到这一点。我能想到的最简单的方法就是使用shell脚本。您可以编写一个小的shell脚本，它只需将任何输入打印到stdout，然后使用unix+(或system)命令从matlab中调用该shell脚本。Jenkins应该能够读取脚本的命令行输出并使用它。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|81428|entityMap^0|2F|4|2M|6|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

There don't seem to be any good ways to do this from within MATLAB. The easiest way I can think of doing this is by using a shell script. You could write a small shell script which would simply print any input to stdout, and then call that shell script from within matlab using the <code>unix</code> (or <code>system</code>) commands. Jenkins should be able to read the command-line output of the script and work with that.

blocks|key|81820|text|我想出了一种方法来做这件事，而且我也在windows上为Jenkins+Matlab接口做这件事。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|81821|基本思想是，您将使用日记命令，然后是尾-f文件，但如果您打开多个matlab实例，则需要一种智能的方法来杀死该尾命令，因为会出现名称冲突。因此，我使用的方法是命名文件log.txt，其中使用的PID是MATLAB的PID，打开时它正在使用。|81822|在MATLAB中有一个无文档的特性，允许你得到它的PID。所以现在，您的批处理文件和MATLAB都知道PID，而不必对执行多个作业时会变得混乱的随机文本文件进行读写。所以PID作为您唯一的标识符。MATLAB还使用尾-f的PID来杀死尾-f以使批处理文件生成，并使用与进程调用相关的命令行详细信息来查找，因为它再次使用了唯一的PID日志文件名。|81823|这使用了一些wmic命令，并且需要Windows+/7或更高版本。使用XP，您可能需要更加努力地获得进程ID，但是仍然有可能。|81824|以下是要做的事情：|81825|1)获取gnu+awk+for+windows：http://gnuwin32.sourceforge.net/packages/gawk.htm|offset|length|81826|2)从windows资源工具包获取tail.exe：http://www.microsoft.com/en-us/download/details.aspx?id=17657|81827|3)确保尾巴和awk在您的路径中(我认为windows资源工具包不会自动将它们放在路径中)|81828|3)创建一个名为matlabrun.bat的批处理文件，如下所示(注意:您需要@echo+off，整个命令也很长，向右滚动。)|81829|@echo+off

:next

del+/f+%25logfilename%25|81832|5)+run.bat文件将执行matlabrun.bat，由于-wait未被传递，matlab将立即返回命令行并执行尾-f命令。这将阻止批处理文件的完成，直到您杀死它。matlabrun.bat返回matlab的PID。|81833|6)另一个重要注意事项:由于您使用的是“”，这将为您提供MATLAB所使用的PID，但默认为c:\windows\system32+32的工作目录。这就是为什么我把工作目录传递给matlab。对于您将哪些参数放入命令字符串中以供matlab运行也有一点特别之处。因此，在命令字符串中使用逗号似乎有问题。因此，我建议不要使用这些，或者想出如何转义它们(可能是%5E，但我只是在matlab+run命令中删除了逗号)。|81834|6)+"test_run.m“文件包含以下代码，用于写入正确的日志文件并杀死正确的尾-f实例。|81835|matlabpid=feature('getpid');

I figured out a way to do this and am also doing it for Jenkins Matlab interface on windows.

Basic idea is that you will use diary command, but then tail -f the file, but you need a smart way to kill the tail command if you open multiple matlab instances because there will be name collisions. So the method I'm using is to name the file log.txt where the PID used is MATLAB's PID it is using when it opens. 

There is an undocumented feature in MATLAB that allows you to get its PID. So now, both your batch file and MATLAB know the PID without having to read/write to a random text file that will get messy when executing multiple jobs. So the PID you use that as your unique identifier. The PID of "tail -f" is also used by MATLAB to kill tail -f to make the batch file die and is found by MATLAB using the commandline details associated with the process invocation since it uses again the unique PID log file name.

This uses some wmic commands and needs Windows Vista/7 or above. With XP you probably have to work harder to get the process ID's but should be still possible.

Here is what to do:

1) Get gnu awk for windows: <a href="http://gnuwin32.sourceforge.net/packages/gawk.htm" rel="nofollow">http://gnuwin32.sourceforge.net/packages/gawk.htm</a>

2) Get tail.exe from windows resource kit: <a href="http://www.microsoft.com/en-us/download/details.aspx?id=17657" rel="nofollow">http://www.microsoft.com/en-us/download/details.aspx?id=17657</a>

3) Make sure tail and awk are in your path (the windows resourece kit I don't think automatically puts them in the path)

3) Create a batch file called matlabrun.bat as follows, (note: you need the @echo off, also the entire command is quite long, scroll right..)

<pre><code>@echo off
wmic process call create "c:\matlab\bin\win64\matlab.exe -r \"cd('c:\jenkins\workspace\test'); workdir=pwd; outpath=[pwd '\output'] ; try; run('C:\MATLAB\work\test_run'); end; quit; \" " | findstr ProcessId | awk "{print $3}" | awk -F";" "{ print $1 }"
</code></pre>

4) Create another batch file called run.bat with:

<pre><code>for /f %%i in ('matlabrun.bat') do (

 echo MATLAB Log... &gt; log%%i.txt

 tail -f log%%i.txt

 set logfilename=log%%i.txt

 goto next

)

:next

del /f %logfilename%
</code></pre>

5) The run.bat file will execute matlabrun.bat and since -wait is not passed, matlab will immediately return to the command line and execute the tail -f command. That will block the batch file from completing until you kill it. matlabrun.bat returns the PID of matlab. 

6) Another important note: since you are using "wmic process create" which will provide you with a PID that MATLAB is using, but will default to a working directory of c:\windows\system32. So that is why I pass the work directory to matlab. wmic process create is also a bit particular about what parameters you put into your command string for matlab to run. So it appears to have a problem with using commas in your command string. So I suggest not to use those, or figure out how to escape them (it might be that ^, works, but I just removed my commas anyway in my matlab run command).

6) The "test_run.m" file contains the following code to write to the correct log file and to kill correct tail -f instance.

<pre><code>matlabpid=feature('getpid');
filename=['log',num2str(matlabpid),'.txt'];
filenamefull=[workdir,'\',filename];

diary(filenamefull);
disp('Script starting...')


%%% put your code here %%%


disp('Script completed...');
diary off;

%%% FIND PID of tail.exe and kill it 
%%% by using the name of the log file in the process command line
[a,b]=dos(['wmic process get Commandline,ProcessId']);
C=textscan(b,'%s','delimiter','\n');C=C{1};
for jj=1:size(C,1),
 if strfind(C{jj},filename),
 D=textscan(C{jj},'%s');D=D{1};
 dos(['taskkill /f /pid ',D{4}]) %kills tail.exe which is the log watcher
 break
 end
end
</code></pre>

7) You start it by doing run.bat. It will go and execute matlab, then start tailing the output while MATLAB runs in real-time. Then when done it will delete the log file.

8) My directory structure / files are in these locations (I'm using win7 64bit):

c:\jenkins\workspace\test\tail.exe

c:\jenkins\workspace\test\awk.exe

c:\jenkins\workspace\test\matlabrun.bat

c:\jenkins\workspace\test\run.bat

c:\matlab\work\test_run.m

c:\matlab\bin\win64\matlab.exe

If you are using 32bit matlab, point it to the win32 directory. To get the correct PID, you need to specify the actualy matlab.exe binary in the win32 or win64 directory.

blocks|key|81483|text|您可以通过将-logfile选项指向Jenkins日志文件来做到这一点。如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|81484|"C:\path\to\matlab.exe"+"-r"+"functionToRun"+"-logfile"+"%25JENKINS_HOME%25\jobs\%25JOB_NAME%25\builds\%25BUILD_NUMBER%25\log"+/wait|code-block|syntax|javascript|81485|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

<pre><code>matlab.exe -nodisplay -nosplash -nodesktop -wait -logfile logfile.txt -r "try script.m ;catch err; disp(err.message); end ; exit"
</code></pre>

I prefer using bash (Execute shell) in Jenkins, then you can tail the log-file while matlab is running.

<pre><code>matlab.exe &lt;...&gt; &amp;
matpid=$!
tail -f logfile.txt &amp;
tailpid=$!
wait $matpid
matexit=$?
kill $tailpid
sleep 1 # Just to make sure kill is done before Jenkins step ends and no zombie processes
exit $matexit
</code></pre>

We're starting Matlab from our <a href="http://jenkins-ci.org" rel="nofollow noreferrer">Jenkins buildserver</a>. As the build may take some time it would be nice to get some log-outputs while matlab is running. Is there a way to print text to standard output? disp, fprintf and java.lang.System.out.printline only write to the matlab console, not to standard output.

<a href="https://stackoverflow.com/questions/4611195/how-to-call-matlab-from-command-line-and-print-to-stdout-before-exiting">Using a logfile </a> or a pipe won't help, as Jenkins only reads from standard-output during a build step.

How can we write log-statements to the standard output while matlab is running?

We're running Matlab 2010b on Windows
