ZGLMTS
Purpose:
ZGLMTS tests ZGGGLM - a subroutine for solving the generalized linear model problem.
Parameters
N
N is INTEGER The number of rows of the matrices A and B. N >= 0.
M
M is INTEGER The number of columns of the matrix A. M >= 0.
P
P is INTEGER The number of columns of the matrix B. P >= 0.
A
A is COMPLEX*16 array, dimension (LDA,M) The N-by-M matrix A.
AF
AF is COMPLEX*16 array, dimension (LDA,M)
LDA
LDA is INTEGER The leading dimension of the arrays A, AF. LDA >= max(M,N).
B
B is COMPLEX*16 array, dimension (LDB,P) The N-by-P matrix A.
BF
BF is COMPLEX*16 array, dimension (LDB,P)
LDB
LDB is INTEGER The leading dimension of the arrays B, BF. LDB >= max(P,N).
D
D is COMPLEX*16 array, dimension( N ) On input, the left hand side of the GLM.
DF
DF is COMPLEX*16 array, dimension( N )
X
X is COMPLEX*16 array, dimension( M ) solution vector X in the GLM problem.
U
