How to save a matrix into a file repeatedly.

Hi there,

I have made a script for generating a set of features (i.e. a double 30x31 matrix). The script would be run several times depends on the numbers of the file in the folder. After each time of the process, I need to save the matrix into a .mat file. However, I have failed to save all the matrix in one file.

For example, the script is run 10 times, so there are 10 30x31 matrixes. The file should be a 300x31 matrix.

I am wondering if everyone would know how to do it??

Thank you :)

Look at this example

for k=1:10
  M=rand(31,30)
  out{k,1}=M
end
out=cell2mat(out)
dlmwrite('file.txt',out)
