slarfx.f(3) LAPACK slarfx.f(3) NAME
slarfx.f - SYNOPSIS
Functions/Subroutines subroutine slarfx (SIDE, M, N, V, TAU, C, LDC, WORK) SLARFX Function/Subroutine Documentation subroutine slarfx (characterSIDE, integerM, integerN, real, dimension( * )V, realTAU, real, dimension( ldc, * )C, integerLDC, real, dimension( * )WORK) SLARFX Purpose: SLARFX applies a real elementary reflector H to a real m by n matrix C, from either the left or the right. H is represented in the form H = I - tau * v * v**T where tau is a real scalar and v is a real vector. If tau = 0, then H is taken to be the unit matrix This version uses inline code if H has order < 11. Parameters: SIDE SIDE is CHARACTER*1 = 'L': form H * C = 'R': form C * H M M is INTEGER The number of rows of the matrix C. N N is INTEGER The number of columns of the matrix C. V V is REAL array, dimension (M) if SIDE = 'L' or (N) if SIDE = 'R' The vector v in the representation of H. TAU TAU is REAL The value tau in the representation of H. C C is REAL array, dimension (LDC,N) On entry, the m by n matrix C. On exit, C is overwritten by the matrix H * C if SIDE = 'L', or C * H if SIDE = 'R'. LDC LDC is INTEGER The leading dimension of the array C. LDA >= (1,M). WORK WORK is REAL array, dimension (N) if SIDE = 'L' or (M) if SIDE = 'R' WORK is not referenced if H has order < 11.
