MATLAB: Sort a cell array based on the number of rows in each cell

Question

Hi, I have an cell array of 6031×1 cell. each cell contain as matrix of different number of rows but with 53 columns.

i want to remove all cells with 1 or 2 rows.

i have tried to use this code to sort the cells and than delete them in a second step:

   NrowsB = cellfun('size',mycellarray,1) ;
  [~, ri] = sort(NrowsB);

but this does not work. Any ideas how to sort the cells or how to delete the cells directly?

Answer 1

Your question is confused: you ask that you want to "sort a cell array based on the number of rows in each cell", but then later you state that you "want to remove all cells with 1 or 2 rows."

So which do you want to do: sort or delete the cell array?

Here is how you can delete those cells:

NrowsB = cellfun('size',mycellarray,1) ;
mycellarray(NrowsB<3) = []

Here is how you can sort those cells:

[~,idx] = sort(NrowsB);
mycellarray = mycellarray(idx);
