slar2v.f-SYNOPSIS

Functions/Subroutines subroutine slar2v (N, X, Y, Z, INCX, C, S, INCC) SLAR2VFunction/Subroutine Documentation subroutine slar2v (integerN, real, dimension( * )X, real, dimension( * )Y, real, dimension( * )Z, integerINCX, real, dimension( * )C, real, dimension( * )S, integerINCC) SLAR2V Purpose: SLAR2V applies a vector of real plane rotations from both sides to a sequence of 2-by-2 real symmetric matrices, defined by the elements of the vectors x, y and z. For i = 1,2,...,n ( x(i) z(i) ) := ( c(i) s(i) ) ( x(i) z(i) ) ( c(i) -s(i) ) ( z(i) y(i) ) ( -s(i) c(i) ) ( z(i) y(i) ) ( s(i) c(i) ) Parameters: N N is INTEGER The number of plane rotations to be applied. X X is REAL array, dimension (1+(N-1)*INCX) The vector x. Y Y is REAL array, dimension (1+(N-1)*INCX) The vector y. Z Z is REAL array, dimension (1+(N-1)*INCX) The vector z. INCX INCX is INTEGER The increment between elements of X, Y and Z. INCX > 0. C C is REAL array, dimension (1+(N-1)*INCC) The cosines of the plane rotations. S S is REAL array, dimension (1+(N-1)*INCC) The sines of the plane rotations. INCC INCC is INTEGER The increment between elements of C and S. INCC > 0.
