I_AMAX(3F)I_AMAX(3F)NAME
idamax, isamax, izamax, icamax - BLAS Maximum index functions
FORTRAN 77 SYNOPSIS
integer function idamax( n, x, incx )
integer incx, n
double precision x( 1 )
integer function isamax( n, x, incx )
integer incx, n
real x( 1 )
integer function izamax( n, x, incx )
integer incx, n
complex*16 x( 1 )
integer function icamax( n, x, incx )
integer incx, n
complex x( 1 )
C SYNOPSIS
Integer idamax( n, x, incx )
Integer incx, n;
double (*x)[ n ];
Integer isamax( n, x, incx )
Integer incx, n;
float (*x)[ n ];
Integer izamax( n, x, incx )
Integer incx, n;
Zomplex (*x)[ n ];
Integer icamax( n, x, incx )
Integer incx, n;
Complex (*x)[ n ];
DESCRIPTION
idamax, isamax, izamax, and icamax, return the index of the maximum value
of vector x. The vector x has length n and increment incx.
For izamax and icamax , the norm of each value is taken as:
Abs( Real( x(i) ) ) + Abs( Imag( x(i) ) )
