问如何在Matlab中将字符串数据转换为整型变量？

EN

>> c = '1234567'

c =

1234567

>> class(c)

ans =

char

>> result = str2num(c)

result =

 1234567

>> class(result)

ans =

double

>> result = str2num(['int32(' c ')'])

result =

 1234567

>> class(result)

ans =

int32

b = cellfun(@(x)str2double(x), total_data);

%Test data
N = 1e4;
textdata = cell(N,1);
for ix = 1:N
    textdata{ix} = num2str(ix);
end

%Convert to integers
dataAsInts = zeros(size(textdata),'int32');
for ix = 1:N
   dataAsInts(ix) = int32(sscanf(textdata{ix},'%d'));
end
