Functions/Subroutines¶
subroutine clascl2 (M, N, D, X, LDX)
CLASCL2 performs diagonal scaling on a vector.
Function/Subroutine Documentation¶
subroutine clascl2 (integer M, integer N, real, dimension( * ) D, complex, dimension( ldx, * ) X, integer LDX)¶
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 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 >= M.
