### NAME[Toc][Back]

dnrm2, snrm2, zdnrm2, csnrm2 - BLAS level ONE Euclidean norm functions.

### SYNOPSIS[Toc][Back]

double precision  dnrm2( n, x, incx )
integer	       incx, n
double precision  x( 1 )

real	       snrm2( n, x, incx )
integer	       incx, n
real	       x( 1 )

double precision  zdnrm2( n, x, incx )
integer	       incx, n
complex*16	       x( 1 )

real	       csnrm2( n, x, incx )
integer	       incx, n
complex	       x( 1 )

### DESCRIPTION[Toc][Back]

DNRM2, SNRM2, ZDNRM2, CSNRM2 compute the Euclidean	norm of	the vector X
of	length N and increment INCX.
nrm2 <--- Sqrt	( Sum( X(i)**2 ) )		   DNRM2  and SNRM2
nrm2 <--- Sqrt	( Sum( conjg( X(i) ) * X(i) ) )	   DZNRM2 and SCNRM2
