CLASCL2 performs diagonal scaling on a vector.
Download CLASCL2 + dependencies [TGZ] [ZIP] [TXT]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.
[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 REAL array, length M Diagonal matrix D, stored as a vector of length M. 
[in,out]  X  X is COMPLEX 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.
