Hello All,
I have a matrix (called my_matrix) which is of size() 256 x 6 x 2000. Could you please let me know how to split this array into six separate .mat files (or some other easier way) each having 256 x 1 x 2000? I tried using for loop as below but it didn't work out.
for i = 1:6
filename[i] = 'my_data[i].mat';
save(filename[i],'my_matrix(:,i,:)';'-mat');
end
Thanks! \ksnf3000

See if this does what you want:
M = randi(99, 10,6, 15); % Create Matrix
C = num2cell(M, [1 3]); % Cell Array
for k1 = 1:size(C,2)
filename = sprintf('my_data%d.mat', k1);
my_matrix = squeeze(C{k1})'
save(filename, 'my_matrix')
end
NOTE— I tested everything except the save call because I didn’t want to have to go back and delete those files. It should work as written.

My pleasure.
I don’t know where the graphics references are coming from. If you’re getting information from a .fig file or a plot, that’s a separate issue and depends on the version of MATLAB you’re using, since this changed significantly beginning with R2014b.
With just the matrix and the cells created from it, this is how I would do it:
M = randi(99, 10,6, 15); % Create Matrix
C = num2cell(M, [1 3]); % Cell Array
Cellmax = cellfun(@(x) max(x(:)), C, 'Uni',0); % Maximum
Cellmin = cellfun(@(x) min(x(:)), C, 'Uni',0); % Minimum
Cellmean = cellfun(@(x) mean(x(:)), C, 'Uni',0); % Mean (Average)
These produce cell arrays as output. To convert them to numeric arrays, use the cell2mat function, for example:
MaxMtx = cell2mat(Cellmax);
and so for the others.

v=rand(4,6,8)
for ii= 1:6
filename=sprintf('my_data%d.mat',ii);
s=v(:,ii,:)
save(filename,'s');
end
