Triangular solve

Description

Triangular solve

Usage

linalg_solve_triangular(A, B, ..., upper, left = TRUE, unitriangular = FALSE)

Arguments

A	tensor of shape ⁠(*, n, n)⁠ or ⁠(*, k, k)⁠ if left=TRUE) where * is zero or more batch dimensions.
B	right-hand side tensor of shape ⁠(*, n, k)⁠
...	Currently ignored.
upper	whether A is an upper or lower triangular matrix.
left	wheter to solve the system AX=B or XA=B
unitriangular	if TRUE, the diagonal elements of A are assumed to be all equal to 1.
