warp.tile_lower_solve(
L: Tile[Float, tuple[int, int]],
y: Tile[Float, tuple[int]],
) → Tile[Float, tuple[int]]#

  • Kernel

Solve for z in Lz = y, where L is a lower triangular matrix.

This performs general forward substitution for a lower triangular system.

Note that computing the adjoint is not yet supported.

Supported datatypes are:

  • float32

  • float64

param L:

A square, non-singular, lower triangular matrix

param y:

A 1D or 2D tile with compatible shape

returns z:

A tile of the same shape as y such that Lz = y
