lapack_lstsq_f32

void lapack_lstsq_f32(const float * A, float * B, int m, int n, int nrhs, int * info)

source edit

Single-precision least-squares solver via QR.

Computes the minimum-2-norm solution of an overdetermined system: $\min_X \|A X - B\|_2$ For tall $A$ (m ≥ n) uses QR; for wide $A$ (m < n) uses LQ. B is overwritten with $X$ in its leading $n$ rows.
