izmax1.f - SYNOPSIS
Functions/Subroutines INTEGER function izmax1 (N, CX, INCX) IZMAX1 Function/Subroutine Documentation INTEGER function izmax1 (integerN, complex*16, dimension( * )CX, integerINCX) IZMAX1 Purpose: IZMAX1 finds the index of the element whose real part has maximum absolute value. Based on IZAMAX from Level 1 BLAS. The change is to use the 'genuine' absolute value. Parameters: N N is INTEGER The number of elements in the vector CX. CX CX is COMPLEX*16 array, dimension (N) The vector whose elements will be summed. INCX INCX is INTEGER The spacing between successive values of CX. INCX >= 1.

zlar2v.f - SYNOPSIS
Functions/Subroutines subroutine zlar2v (N, X, Y, Z, INCX, C, S, INCC) ZLAR2V Function/Subroutine Documentation subroutine zlar2v (integerN, complex*16, dimension( * )X, complex*16, dimension( * )Y, complex*16, dimension( * )Z, integerINCX, double precision, dimension( * )C, complex*16, dimension( * )S, integerINCC) ZLAR2V Purpose: ZLAR2V applies a vector of complex plane rotations with real cosines from both sides to a sequence of 2-by-2 complex Hermitian matrices, defined by the elements of the vectors x, y and z. For i = 1,2,...,n ( x(i) z(i) ) := ( conjg(z(i)) y(i) ) ( c(i) conjg(s(i)) ) ( x(i) z(i) ) ( c(i) -conjg(s(i)) ) ( -s(i) c(i) ) ( conjg(z(i)) y(i) ) ( s(i) c(i) ) Parameters: N N is INTEGER The number of plane rotations to be applied. X X is COMPLEX*16 array, dimension (1+(N-1)*INCX) The vector x; the elements of x are assumed to be real. Y Y is COMPLEX*16 array, dimension (1+(N-1)*INCX) The vector y; the elements of y are assumed to be real. Z Z is COMPLEX*16 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 DOUBLE PRECISION array, dimension (1+(N-1)*INCC) The cosines of the plane rotations. S S is COMPLEX*16 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.
