I have a matrix cA. I want to input values into a matrix A that are a scalar (1E-14) divided by each element in a row of cA that is not equal to zero.
I have so far:
but this uses every column in the ith row. Some of the cell values in the columns are zero so the result is infinity in some cells/elements of A. I would only like to input a value into an element of A if cA(i,j) > 0. Alternatively, if the result is infinity, then just input a zero into that element of A.
