In this example, values in an array are normalized to be in the range 0 to 1. The normalized values are calculated using the maximum and minimum values from the original array.
import Accelerate
// Create random data
var data = [Float](repeating: 0, count: 10)
for i in 0..<data.count {
data[i] = .random(in: 2...14)
}
print(data)
// Normalize the data to range 0 to 1 using formula
// f = (s - s_min) / (s_max - s_min)
let max = data.max()!
let min = data.min()!
let u = vDSP.add(min * -1, data)
let dataNorm = vDSP.divide(u, max - min)
print(dataNorm)
This prints the following for the original data array:
