dlarscl2.f(3) LAPACK dlarscl2.f(3)NAMEdlarscl2.f-SYNOPSISFunctions/Subroutines subroutine dlarscl2 (M, N, D, X, LDX) DLARSCL2 performs reciprocal diagonal scaling on a vector.Function/Subroutine Documentation subroutine dlarscl2 (integerM, integerN, double precision, dimension( * )D, double precision, dimension( ldx, * )X, integerLDX) DLARSCL2 performs reciprocal diagonal scaling on a vector. Purpose: DLARSCL2 performs a reciprocal diagonal scaling on an vector: x <-- inv(D) * x where the diagonal matrix D is stored as a vector. Eventually to be replaced by BLAS_dge_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 DOUBLE PRECISION array, dimension (M) Diagonal matrix D, stored as a vector of length M. X X is DOUBLE PRECISION 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. Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
