Hi all, I have a 309 * 5956 cell array of same type and same length. however most of the elements are empty.

However using cell2array to convert this matrix to numerical it gives me error as:

cell2mat(all_i_dis) Error using cat Dimensions of matrices being concatenated are not consistent.

Error in cell2mat (line 79) m = cat(1,m{:});

any idea is highly appreciated.

Accepted answer

A={ 1 , 2 ; [], 4}; cell2mat(A);

The result

Error using cat Dimensions of matrices being concatenated are not consistent. Error in cell2mat (line 87) m = cat(2,m{:});

To use cell2mat, all cells must be the same size and same class

Thanks Azzi, so if I am right I have to convert all of the [] to 0 maybe? Is there anyway to do that?

Thanks

I know the way through a loop like

for n=1:length(mycellarray) if isempty(mycellarray{n}) mycellarray{n}=0; end end

but is there any other efficient way instead of loop?

Opportunities for recent engineering grads.
