Function

vDSP_zvzsml(_:_:_:_:_:_:)

Multiplies a single-precision complex scalar value by a single-precision complex vector.

Declaration

func vDSP_zvzsml(_ __A: UnsafePointer<DSPSplitComplex>, _ __IA: vDSP_Stride, _ __B: UnsafePointer<DSPSplitComplex>, _ __C: UnsafePointer<DSPSplitComplex>, _ __IC: vDSP_Stride, _ __N: vDSP_Length)

Parameters

__A

Single-precision complex input vector.

__IA

Stride for A.

__B

Pointer to single-precision complex input scalar.

__C

Single-precision complex output vector.

__IC

Stride for C.

__N

The number of elements to multiply.

Discussion

This function calculates the products of the first N elements of A and the scalar value B, writing the result to C:

A diagram showing the operation of the vDSP_vsmul function. There are three rows. The top row represents the first input, vector A. The second row represents the second input, scalar 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;
