lapack_solve_f32

void lapack_solve_f32(float * A, float * B, int n, int nrhs, int * info)

Single-precision linear system solver $A X = B$ .

Computes the LU factorization of $A$ (with partial pivoting) and solves for $X$ in place of $B$ . Used for square invertible systems.

Math

$A X = B \;\;\Longrightarrow\;\; X = A^{-1} B$
