def stfsm(alpha, a, b, transr = N, side = L, uplo = U, trans = N, diag = N, overwrite_b = 0)

Solve a triangular system whose matrix is in rectangular full packed (RFP) storage (LAPACK stfsm).

Solves op(A) @ x = alpha * b when side is 'L', or x @ op(A) = alpha * b when it is 'R'.

alpha : float: Scalar the right-hand side is multiplied by.
a : ndarray: The triangle of A in RFP storage. Its order is the number of rows of b when side is 'L', its number of columns when 'R', and its length is order * (order + 1) / 2.
b : ndarray: Right-hand side of shape (m, n).
transr : str, optional: 'N' for the normal RFP layout, 'T' for the transposed one. Default is 'N'.
side : str, optional: 'L' for op(A) @ x, 'R' for x @ op(A). Default is 'L'.
uplo : str, optional: 'U' if the matrix is upper triangular, 'L' if lower. Default is 'U'.
trans : str, optional: 'N' for op(A) = A, 'T' for its transpose. Default is 'N'.
diag : str, optional: 'U' if A has a unit diagonal, 'N' otherwise. Default is 'N'.
overwrite_b : int, optional: If nonzero, b may be overwritten in place. Default is 0.
