Hi all,

I 'd like to create a cell array made of x columns and y rows (in my case 10 and 3, respectively), where each x,y position contains a vector of 1x200 NaN. I'd like to find something smarter and nicer than just something like this:

res={nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) ;nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200); nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200) nan(1,200)};

Thank you so much to the community.

If all the vectors in the cell array are the same size, why not use a matrix instead of a cell array. It will make all subsequent operations much easier.

I.e. create a 10x3x200 matrix instead:

res = nan(10, 3, 200);
