(S|D)LAS2¶

Single and double LAS2.

Description¶

Compute singular values for the 2x2 triangular matrix:

$\left[ \begin{matrix} \fvar{F} & \fvar{G} \\ 0 & \fvar{H} \\ \end{matrix} \right]$

LAPACK Interface¶

void slas2(const float *F, const float *G, const float *H, float *SSMIN, float *SSMAX);

void dlas2(const double *F, const double *G, const double *H, double *SSMIN, double *SSMAX);

Arguments¶

F	Element of input matrix
G	Element of input matrix
H	Element of input matrix
SSMIN	Smallest singular value
SSMAX	Largest singular value
