INTEGER function icmax1 (integerN, complex, dimension( * )CX, integerINCX)

ICMAX1 finds the index of the vector element whose real part has maximum absolute value.

Purpose:

 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.

 

Parameters:

N

 N is INTEGER

 The number of elements in the vector CX.

CX

 CX is COMPLEX array, dimension (N)
