lapack_solve_triangular_f32

void lapack_solve_triangular_f32(const float * A, float * B, int n, int nrhs, bool upper, bool unit, int * info)

Single-precision triangular linear solve.

Solves $A X = B$ where $A$ is triangular. Selects upper or lower triangle and whether the diagonal is implicit unit. B is overwritten with $X$ .

Math

$A X = B \;\;\text{with $A$ triangular}$
