INTEGER FUNCTION ICMAX1( N, CX, INCX ) INTEGER INCX, N COMPLEX CX( * )
ICMAX1 finds the index of the element whose real part has maximum absolute value. Based on ICAMAX from Level 1 BLAS. The change is to use the 'genuine' absolute value. Contributed by Nick Higham for use with CLACON.
N (input) INTEGER The number of elements in the vector CX. CX (input) COMPLEX array, dimension (N) The vector whose elements will be summed. INCX (input) INTEGER The spacing between successive values of CX. INCX >= 1.
