matlab中若是想从循环语句中直接返回该怎么弄

please use the break order

for Example

The example below shows a while loop that reads the contents of the file fft.m into a MATLAB? character array. A break statement is used to exit the while loop when the first empty line is encountered. The resulting character array contains the M-file help for the fft program.

fid = fopen('fft.m','r');
s = '';
while ~feof(fid)
line = fgetl(fid);
if isempty(line), break, end
s = strvcat(s,line);
end
disp(s)

that's ok

使用save语句 如 save('matrix.dat',x) 如果每次循环的结果都保存到不同的文件中，可以用 i=i+1; save(strcat('matrix',num2str(i),'.dat'),x)
