Function

vDSP_zrvaddD(_:_:_:_:_:_:_:)

Adds a double-precision complex vector to a double-precision real vector.

Declaration

func vDSP_zrvaddD(_ __A: UnsafePointer<DSPDoubleSplitComplex>, _ __IA: vDSP_Stride, _ __B: UnsafePointer<Double>, _ __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 real 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 sums of the first N complex elements of A to the corresponding real elements of B, writing the result to C:

A diagram showing the operation of the vDSP_zrvadd function. There are three rows. The top row represents the first input, vector A. The second row represents the second input, vector B. The bottom row represents the output, vector C. The diagram has connecting lines from the input vectors to the output vector indicating the relationships between the inputs and output.

The operation is:

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