Hi

I have a 1x6 cell that is:

    Columns 1 through 6
        [2x1195 double]    [4x1195 double]    [2x1195 double]    [4x752 double]    [4x694 double]  [3x695 double]

and I need to convert it to a 19x1 cell that is:

 [1x1195 double]
 [1x1195 double]      
 [1x1195 double]
 [1x1195 double]
 [1x1195 double]
 [1x1195 double]
 [1x1195 double]
 [1x1195 double]    
 [1x752 double] 
 [1x752 double] 
 [1x752 double] 
 [1x752 double]    
 [1x694 double]
 [1x694 double]
 [1x694 double]
 [1x694 double]  
 [1x695 double]
 [1x695 double]
 [1x695 double]

Meaning each row of a "inner" cell becomes the row of the "outer" cell. The first two rows are the 2 rows of Column 1, and so on.

I have already tried the function reshape, cell2mat, mat2cell, cat, but I haven't been able to make it work.

Thank you

在 MATLAB Online 中打开

C = ... % Your input
D = cell(size(C))
for k = 1:numel(C)
  D{k} = num2cell(C{k}, 2);    % [EDITED, {k} added]
end
Result = cat(1, D{:});

I got it to work as:

C = my cell;
D = cell(size(C));
for k = 1:numel(C)
  D{1,k} = num2cell(C{k}, 2);
end
Result = cat(1, D{:});

Thanks

Possibly a cleaner version of the above:

D = cellfun(@(c) num2cell(c, 2), C, 'UniformOutput', false);
Result = vertcat(D{:});
