Class

MPSMatrixSolveTriangular

A kernel for computing the solution of a linear system of equations using a triangular coefficient matrix.

Declaration

class MPSMatrixSolveTriangular : MPSMatrixBinaryKernel

Overview

This kernel finds the solution matrix to the system op(A) * X = alpha * B or X * op(A) = alpha * B, where:

  • A is either an upper or lower triangular matrix

  • op(A) is either Aᵀ or A

  • X is the resulting matrix of solutions

  • B is the array of right hand sides for which the equations are to be solved
