vDSP_zvmul
Multiplies two complex vectors, optionally conjugating one of them; single precision.
Declaration
void vDSP_zvmul(const DSPSplitComplex *__A, vDSP_Stride __IA, const DSPSplitComplex *__B, vDSP_Stride __IB, const DSPSplitComplex *__C, vDSP_Stride __IC, vDSP_Length __N, int __Conjugate);Parameters
- __A:
Single-precision complex input vector.
- __IA:
Stride for
A. - __B:
Single-precision complex input vector.
- __IB:
Stride for
B. - __C:
Single-precision complex output vector.
- __IC:
Stride for
C. - __N:
The number of elements to process.
- __Conjugate:
Set this parameter to
1for normal or-1for conjugate multiplication, respectively. Results are undefined for other values; represented byFin the discussion
Discussion
If Conjugate = 1, this function multiplies the first N complex elements of A by corresponding complex elements of B. If Conjugate = -1, it multiplies the complex conjugates of the first N complex elements of A by corresponding complex elements of B. In either case, the complex results are left in C:
