rleqs, cleqs

These functions implements an interface for the LAPACK functions DGESV, ZGESV, DGELS and ZGELS.

Usage

rleqs(A, B {, alg}):

A

left side MxN matrix x

B

right side vector or MxL matrix (for multiple solutions)

alg

select a LAPACK algorithm to be used

alg=0	...	use DGESV if M=N and DGELS otherwise
alg=1	...	use always DGESV, M must be equal to N
alg=2	...	use always DGELS

Notes

• The function cleqs(A, B {, alg}) has the same arguments and result as rleqs, but the vectors/matrices A, B and X are complex.
• rleqs calls the LAPACK functions DGESV and DGELS, while cleqs calls ZGESV and ZGELS
