NAME

SYNOPSIS
Functions/Subroutines
COMPLEX *16 function zladiv (X, Y)
ZLADIV performs complex division in real arithmetic, avoiding unnecessary overflow.

Function/Subroutine Documentation
ZLADIV performs complex division in real arithmetic, avoiding unnecessary overflow.

Purpose:

ZLADIV := X / Y, where X and Y are complex.  The computation of X / Y
will not overflow on an intermediary step unless the results
overflows.

Parameters:
X

X is COMPLEX*16

Y

Y is COMPLEX*16
The complex scalars X and Y.

NAME
zlartg.f -

SYNOPSIS
Functions/Subroutines
subroutine zlartg (F, G, CS, SN, R)
ZLARTG generates a plane rotation with real cosine and complex sine.

Function/Subroutine Documentation
subroutine zlartg (complex*16F, complex*16G, double precisionCS, complex*16SN, complex*16R)
ZLARTG generates a plane rotation with real cosine and complex sine.

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.
