void zlsolve | ( | int | ldm, |
int | ncol, | ||
doublecomplex * | M, | ||
doublecomplex * | rhs | ||
) |
Solves a dense UNIT lower triangular system. The unit lower triangular matrix is stored in a 2D array M(1:nrow,1:ncol). The solution will be returned in the rhs vector.
void zmatvec | ( | int | ldm, |
int | nrow, | ||
int | ncol, | ||
doublecomplex * | M, | ||
doublecomplex * | vec, | ||
doublecomplex * | Mxvec | ||
) |
Performs a dense matrix-vector multiply: Mxvec = Mxvec + M * vec. The input matrix is M(1:nrow,1:ncol); The product is returned in Mxvec[].
void zusolve | ( | int | ldm, |
int | ncol, | ||
doublecomplex * | M, | ||
doublecomplex * | rhs | ||
) |
Solves a dense upper triangular system. The upper triangular matrix is stored in a 2-dim array M(1:ldm,1:ncol). The solution will be returned in the rhs vector.
