Gan_Bool gan_mat_qr ( Gan_Matrix * A,

Gan_Matrix * Q,

Gan_SquMatrix * R,

double * work,

unsigned long work_size

)

Performs QR decomposition of matrix.

Returns:
GAN_TRUE on success, GAN_FALSE on failure.
Performs QR decomposition of matrix A:
$A = Q \: R$
where A is an $ m $ by $ n $ matrix where $m \geq n$ , Q is an orthogonal matrix and R is an upper triangular matrix.
work is a workspace array of size work_size, which should be $\geq m+\mbox{max}(1,n)$ .
R may be passed as NULL, in which case the triangular factor is not computed.

Gan_Bool gan_matf_qr ( Gan_Matrix_f * A,

Gan_Matrix_f * Q,

Gan_SquMatrix_f * R,

float * work,

)
