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];
