`scipy.linalg._fblas:strsm`

Signature

def strsm(alpha, a, b, side = 0, lower = 0, trans_a = 0, diag = 0, overwrite_b = 0)

Solve the triangular system op(a)@x = alpha*b for x (BLAS strsm).

alpha : float: Scalar multiplier.
a : ndarray: Triangular matrix; only the triangle selected by lower is referenced.
b : ndarray: Input/output matrix.
side : int, optional: If 0, a multiplies from the left; if 1, from the right. Default is 0.
lower : int, optional: If 0, the upper triangle is used; if 1, the lower. Default is 0.
trans_a : int, optional: Operation on a: 0 none, 1 transpose, 2 conjugate transpose. Default is 0.
diag : int, optional: If 0, the matrix has a non-unit diagonal; if 1, it is unit-triangular. Default is 0.
overwrite_b : int, optional: If nonzero, b may be overwritten in place. Default is 0.

b : ndarray: The solution x (or the solution of x@op(a) = alpha*b if side=1).
