## Function/Subroutine Documentation

### subroutine slascl2 (integerM, integerN, real, dimension( * )D, real, dimension( ldx, * )X, integerLDX)

**SLASCL2** performs diagonal scaling on a vector.

**Purpose:**

SLASCL2 performs a diagonal scaling on a vector: x <-- D * x where the diagonal matrix D is stored as a vector. Eventually to be replaced by BLAS_sge_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 D and X. N >= 0.

*D*D is REAL array, length M Diagonal matrix D, stored as a vector of length M.

*X*X is REAL 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 >= 0.
