ZLASCL2 performs diagonal scaling on a matrix.
Function/Subroutine Documentation
subroutine zlascl2 (integer m, integer n, double precision, dimension( * ) d, complex*16, dimension( ldx, * ) x, integer ldx)
ZLASCL2 performs diagonal scaling on a matrix.
Purpose:
ZLASCL2 performs a diagonal scaling on a matrix: x <-- D * x where the DOUBLE PRECISION diagonal matrix D is stored as a vector. Eventually to be replaced by BLAS_zge_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 DOUBLE PRECISION array, length M Diagonal matrix D, stored as a vector of length M.
X
X is COMPLEX*16 array, dimension (LDX,N) On entry, the matrix X to be scaled by D. On exit, the scaled matrix.
LDX
LDX is INTEGER The leading dimension of the matrix X. LDX >= M.
