NAME scnrm2 - Return the Euclidian norm of a vector. SYNOPSIS REAL FUNCTION SCNRM2 (N, X, INCX) INTEGER INCX, N COMPLEX X( * ) #include <sunperf.h> double scnrm2(int n, complex *cx, int incx) ; PURPOSE SCNRM2 - Return the Euclidian norm of a vector x where x is an n-vector. PARAMETERS N - INTEGER. On entry, N specifies the number of elements in the vector. N must be at least one for the sub- routine to have any visible effect. Unchanged on exit. X - COMPLEX array of DIMENSION at least ( 1 + ( m - 1 )*abs( INCX ) ). On entry, the incremented array X must contain the vector x. Unchanged on exit. INCX - INTEGER. On entry, INCX specifies the increment for the elements of X. INCX must be positive. Unchanged on exit.
