BLAS Level 2 operations for complex ndarrays

Usage

This library implements the basic matrix-vector operations of the Level 2 Basic Linear Algebra Subprograms (BLAS).

Note: It's possible to accomplish the lower triangular functions with the upper triangular version plus flipping and unflipping dimensions, but that's a little convoluted. Instead, the lower triangular versions are suffixed with _lower just to keep it really simple.

gemv( alpha_r, alpha_i, A_r, A_i, x_r, x_i, beta_r, beta_i, y_r, y_i )

Calculate y <- alpha*A*x + beta*y

trmv( A_r, A_i, x_r, x_i, isLower )

Calculate x <- A*x for the upper triangular matrix A. Data below the diagonal is ignored. If isLower is true, uses the lower triangular portion of A instead.

trsv( A_r, A_i, x_r, x_i, isLower )

Calculate x <- A^-1 x for the upper triangular matrix A. Data below the diagonal is ignored. If isLower is true, uses the lower triangular portion of A instead.
