我发现matlab符号工具箱自动将数字转换成分数。对于短期而言,这是可以的,但对于复杂的项,这可能会导致更长的项和更高的计算成本。
让我们用一个简单的例子来描述它:
syms x
a=0.1; % a is double
b=a*x;
结果:
b=
x/10
但是我不想让Matlab转换这种格式的结果,有什么办法让matlab停止这样做吗?(我不想再次使用vpa来转换结果)。
假设我有一个3xK大小的值need_find = [1 3 4]和一个矩阵A。我想在A的对应行上找到need_find的值。如何在matlab中应用矢量化解而不是迭代每一行?
如预期那样详细说明;
A = [1 3 4; 1 3 5; 3 4 5];
my_method_do_what_I_want(A,need_find);
方法返回
ans = [1;2;2]
% so I find the index of each element of need_find at corresponding row at A
长话短说:在第1行搜索1,在row2搜索3,在row3搜索4
我将Ubuntu12.04升级到14.04,现在当我从命令提示符运行matlab时,我得到了(它在12.04上运行得很好)

我遇到了一个问题。我必须在linux上使用MATLAB。我需要将数据从MATLAB解析到Linux,反之亦然。
举个例子
这一切都是在写的
basic.sh
this basic.sh has to be opened in MATLAB
s=3 # is defined is MATLAB
##########################
for (( p=1 ; p<5; p++ )) # from here starts the loop in Linux

我正在尝试通过一个低通滤波器传递我的数据,低通滤波器的截止频率为C++中的1 Hz。为此,我通过Matlab设计了一个kaiser窗,得到了20个系数。这是我的Matlab代码:
fc = 1; % cutoff frequency 1 Hz
Wn = (2/Fs)*fc;
b = fir1(20,Wn,'low',kaiser(21,3));
为了理解如何使用C++应用此滤波器,我使用作为应用低通滤波器的示例。以下是链接中给出的代码。
