Specifies the diagonal to sum.
The diagonal is specified by the
offset parameter where zero is the main diagonal, values greater than one refer to diagonals above the main diagonal (
A[i,i+offset]), and values less than one refer to diagonals below the main diagonal (
If offset is out of the bounds of the matrix
0 is returned.
Solves the system of equations x = alpha * T⁻¹ * x for x where x is a dense vector and T is a triangular sparse matrix, with all operands containing double-precision values.
Solves the system of equations x = alpha * T⁻¹ * x for x where x is a dense vector and T is a triangular sparse matrix, with all operands containing single-precision values.
Computes the outer product of the dense vector x and the sparse vector y, with both operands containing single-precision values.
Permutes the columns of the single-precision sparse matrix A based on the provided permutation array.
