__CSingle-precision complex output vector.
__ICAddress stride for
C.__NThe number of elements to process.
Discussion
The functions in this group populate a vector with a specified scalar value.
The following code shows how to clear the array c, setting the value of each element to pi:
let n = vDSP_Length(10)
let stride = vDSP_Stride(1)
var a = Float.pi
var c = [Float](repeating: .nan,
count: Int(n))
vDSP_vfill(&a,
&c,
stride,
n)
// Prints "[3.1415925, 3.1415925, 3.1415925,
// 3.1415925, 3.1415925, 3.1415925,
// 3.1415925, 3.1415925, 3.1415925,
// 3.1415925]"
print(c)
