Function/Subroutine Documentation
subroutine clascl2 (integerM, integerN, real, dimension( * )D, complex, dimension( ldx, * )X, integerLDX)
CLASCL2 performs diagonal scaling on a vector.
Purpose:
CLASCL2 performs a diagonal scaling on a vector:
x <-- D * x
where the diagonal REAL matrix D is stored as a vector.
Eventually to be replaced by BLAS_cge_diag_scale in the new BLAS
standard.
Parameters:
M
M is INTEGER
The number of rows of D and X. M >= 0.
N
N is INTEGER
The number of columns of D and X. N >= 0.
D
D is REAL array, length M
Diagonal matrix D, stored as a vector of length M.
X
X is COMPLEX array, dimension (LDX,N)
On entry, the vector X to be scaled by D.
On exit, the scaled vector.
LDX
LDX is INTEGER
The leading dimension of the vector X. LDX >= 0.
