vDSP_svdiv

Declaration

void vDSP_svdiv(const float *__A, const float *__B, vDSP_Stride __IB, float *__C, vDSP_Stride __IC, vDSP_Length __N);

Parameters

• __A:

  Pointer to single-precision real input scalar.

• __B:

  Single-precision real input vector.

• __IB:

  Stride for B.

• __C:

  Single-precision real output vector.

• __IC:

  Stride for C.

• __N:

  The number of elements to process.

Discussion

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

The operation is:

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

The following code shows an example of using vDSP_vsdiv:

let stride = vDSP_Stride(1)

var a: Float = 2
let b: [Float] = [1, 2, 4, 5]


let n = vDSP_Length(b.count)

var c = [Float](repeating: 0,
                count: b.count)

vDSP_svdiv(&a,
           b, stride,
           &c, stride,
           n)

// Prints "[2, 1, 0.5, 0.4]"
print(c)
