Computes complex exponent of real vector elements (cosine and sine of real vector elements combined to complex value).
FORTRAN:
call vccis( n, a, y )
call vmccis( n, a, y, mode )
call vzcis( n, a, y )
call vmzcis( n, a, y, mode )
C:
vcCIS( n, a, y );
vmcCIS( n, a, y, mode );
vzCIS( n, a, y );
vmzCIS( n, a, y, mode );
