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 asrleqs
, but the vectors/matrices A, B and X are complex. rleqs
calls the LAPACK functions DGESV and DGELS, whilecleqs
calls ZGESV and ZGELS
