zlartg.f(3) LAPACK zlartg.f(3)NAMEzlartg.f -SYNOPSISFunctions/Subroutines subroutine zlartg (F, G, CS, SN, R) ZLARTG Function/Subroutine Documentation subroutine zlartg (complex*16F, complex*16G, double precisionCS, complex*16SN, complex*16R) ZLARTG Purpose: ZLARTG generates a plane rotation so that [ CS SN ] [ F ] [ R ] [ __ ] . [ ] = [ ] where CS**2 + |SN|**2 = 1. [ -SN CS ] [ G ] [ 0 ] This is a faster version of the BLAS1 routine ZROTG, except for the following differences: F and G are unchanged on return. If G=0, then CS=1 and SN=0. If F=0, then CS=0 and SN is chosen so that R is real. Parameters: F F is COMPLEX*16 The first component of vector to be rotated. G G is COMPLEX*16 The second component of vector to be rotated. CS CS is DOUBLE PRECISION The cosine of the rotation. SN SN is COMPLEX*16 The sine of the rotation. R R is COMPLEX*16 The nonzero component of the rotated vector. Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
