Subtracts a double-precision real vector from a double-precision complex vector.


func vDSP_zrvsubD(_ __A: UnsafePointer<DSPDoubleSplitComplex>, _ __IA: vDSP_Stride, _ __B: UnsafePointer<Double>, _ __IB: vDSP_Stride, _ __C: UnsafePointer<DSPDoubleSplitComplex>, _ __IC: vDSP_Stride, _ __N: vDSP_Length)



Double-precision complex input vector.


Stride for A.


Double-precision real input vector.


Stride for B.


Double-precision complex output vector.


Stride for C.


The number of elements to process.


This function subtracts the first N real elements of B from corresponding complex elements of A, writing the result to C:

A diagram showing the operation of the vDSP_zrvsub 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];
