vDSP_zvcmulD(_:_:_:_:_:_:_:)

Declaration

func vDSP_zvcmulD(_ __A: UnsafePointer<DSPDoubleSplitComplex>, _ __IA: vDSP_Stride, _ __B: UnsafePointer<DSPDoubleSplitComplex>, _ __IB: vDSP_Stride, _ __C: UnsafePointer<DSPDoubleSplitComplex>, _ __iC: vDSP_Stride, _ __N: vDSP_Length)

Parameters

__A

Double-precision complex input vector.

__IA

Stride for A.

__B

Double-precision complex input vector.

__IB

Stride for B.

__C

Double-precision complex output vector.

__IC

Stride for C.

__N

The number of elements to process.

Discussion

This function calculates the products of the first N complex conjugates of A by the corresponding complex elements of B, writing the result to C:

The operation is:

 for (n = 0; n < N; ++n)
    C[n] = conj(A[n]) * B[n];
