MATLAB: Reading data from cell array

cell arraysMATLAB

I have a cell array that contains all the data. A{1,1}, A{2,1},…A{37,1}.

Now, I want to extract the first row from A{1,1}, A{2,1},…A{37,1} and then combine all the 37 rows in one mat file. How can I do that?

C = cell2mat(cellfun(@(x) x(1,:), A, 'un',0));
save mymat.mat C

MATLAB: Reading data from csv files

%your original code, slightly modified
csvfiles = dir('*.csv'); 
filescontent = cell(numel(csvfiles), 1);
for i = 1:numel(csvfiles)
    filescontent{i} = csvread(csvfiles(i).name);
end
%write rows of matrices into mat file
destfolder = 'C:\somewhere\somefolder';
allcontent = cat(3, filescontent{:});  %concatenate all matrices into a 3D matrix
%save rows of each matrix into a mat file (as variable rows)
for rowidx = 1:size(allcontent, 1)
    rows = permute(allcontent(rowidx, :, :), [3 2 1]);  %extract rows.Permute so each matrix is a row of rows
    save(fullfile(destfolder, sprintf('row%d.mat', rowidx)), rows);
end
