If a=[3.6910 4.5873 0 0 0;
0 7.2707 0 0 3.7516;
0 0 0 0 0]
I want to count the number of non zero elements present in every row and column
I tried with the following command numel(a) where it gives the entire number of elements present in a.
Could anyone please help me on this.

Try this
zerosInColumn = sum(a ~= 0, 1);
zerosInRow = sum(a ~= 0, 2);
