ZLASCL2
Download ZLASCL2 + dependencies [TGZ] [ZIP] [TXT]ZLASCL2 performs a diagonal scaling on a vector: 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.
[in] | M | M is INTEGER The number of rows of D and X. M >= 0. |
[in] | N | N is INTEGER The number of columns of D and X. N >= 0. |
[in] | D | D is DOUBLE PRECISION array, length M Diagonal matrix D, stored as a vector of length M. |
[in,out] | X | X is COMPLEX*16 array, dimension (LDX,N) On entry, the vector X to be scaled by D. On exit, the scaled vector. |
[in] | LDX | LDX is INTEGER The leading dimension of the vector X. LDX >= 0. |
