lascl2 - lascl2: diagonal scale matrix, A = D A
subroutine clascl2 (m, n, d, x, ldx)
CLASCL2 performs diagonal scaling on a matrix. subroutine
dlascl2 (m, n, d, x, ldx)
DLASCL2 performs diagonal scaling on a matrix. subroutine
slascl2 (m, n, d, x, ldx)
SLASCL2 performs diagonal scaling on a matrix. subroutine
zlascl2 (m, n, d, x, ldx)
ZLASCL2 performs diagonal scaling on a matrix.
CLASCL2 performs diagonal scaling on a matrix.
Purpose:
CLASCL2 performs a diagonal scaling on a matrix: x <-- D * x where the diagonal REAL matrix D is stored as a matrix. Eventually to be replaced by BLAS_cge_diag_scale in the new BLAS standard.
Parameters
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 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.
