In page 2756 of the Intel MKL Reference Manual(2007), it is said that CSR format for sparse matrix A consists of four arrays,which are called the

*values*,*columns*,*pointerB*, and*pointerE*arrays, and that the length of*pointerB*array is equal to the number of rows in A. Besides, element j of*pointerB*array gives the index into the values array that contains the first non-zero element in a row j of A.So we can deduce that every row of A must have at least one non-zero element.The problem is, what would happen if some rows of A consist of all zeros?
