Splitting a Matrix and saving results
1 view (last 30 days)

I have a matrix (35x5461). I need to split it into 127 matrices of (35x43)
Then each matrix needs to be saved as an ascii with a given prefix, followed by the matrix number
eg data0001.txt, data0002.txt, data0003.txt etc
I've tried using cell2mat with no luck, and am totally stuck on the outputs, any advice would be greatly appreciated

You can use a reshape to help isolate your matrices.
x = reshape(your_matrix,35,43,127);
Then x(:,:,k) is the k'th individual matrix.
The filename can be created with:
fname = sprintf('data%04d.txt',k);
But do you really need the data spit in separate files like this? It will be a pain to read them all in and combine them into a single matrix later on. Can't you just save the reshaped matrix, and then read in the whole thing and pick off your x(:,:,k) part for processing? What program is reading this data downstream?

E.g.,
x = reshape(your_matrix,35,43,127);
for k=1:127
individual_matrix = x(:,:,k);
fname = sprintf('data%04d.txt',k);
% write the variable individual_matrix to the file fname here
end
