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.

在 MATLAB Online 中打开

Try this

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