| Function | Largest complex vector element in terms of the sum |Re| + |Im| |
|
| Syntax C/C++ | #include <VCFstd.h>
fComplex VCF_sabsmax( cfVector X, ui size); |

Alternative syntax (obsolete, but still supported):
procedure VCF_sabsmax( var RetVal:fComplex; X:cfVector; size:UIntSize );

| Description | By the criterion of the sum |Re| + |Im|, the largest element of a cartesian complex vector is found and returned. In many applications, this function may serve as a much faster replacement for VCF_cabsmax. The latter function uses the absolute value, sqrt(Re2 + Im2), as its criterion. |
