let stride = vDSP_Stride(1)
var a: Float32 = 0.0
var b: Float32 = 1.0
var c = [Float32](repeating: 0,
count: Int(vDSP_Length(88200)))

Last active May 27, 2024 00:50
Generates two random values within the same range, ensuring the second value lies outside the tolerance range of the first.
import SwiftUI
func scale(oldMin: Double, oldMax: Double, value: Double, newMin: Double, newMax: Double) -> Double {
return ((value - oldMin) / (oldMax - oldMin)) * (newMax - newMin) + newMin
}
struct ContentView: View {
@State private var firstAngles: [Double] = []
@State private var secondAngles: [Double] = []
@State private var minusThresholdAngles: [Double] = []

theoknock / DispatchGroup.swift
Last active May 16, 2024 19:46
Using a serial and global dispatch queue to synchronize calls to functions that should be executed one after another, preventing overlap.
import Foundation
public func randomizeDurationSplits(group: DispatchGroup? = nil, completion: @escaping ([[Double]]) -> Void) {
group?.enter()
DispatchQueue.global().async {
let dyad0harmony0: Double = Double.random(in: durationLowerBound ... durationUpperBound)
var dyad1harmony0: Double = dyad0harmony0
repeat {

theoknock / ConcentricCircularArrayView.swift
Last active May 10, 2024 09:35
A SwiftUI view consisting of a specified number of Circle() views, each with a diameter matching the standard Slider() "thumb" image (30 points), arranged in a perfect circle with an adjustable radius calculated to space them equidistantly, incorporating additional spacing between each circle.
import SwiftUI
struct CircularArrayView: View {
private let diameter: CGFloat = 30
var numberOfCircles: Int = 12
var spacing: CGFloat = 1.0
// Ensures the number of circles is always even
private var evenNumberOfCircles: Int {
numberOfCircles % 2 == 0 ? numberOfCircles : numberOfCircles + 1

return Color(hue: CGFloat(angle / 360.0), saturation: 1.0, brightness: 1.0, opacity: 1.0)

}
func blackColor() -> Color {
return Color.init(uiColor: .black) // return Color(hue: CGFloat(hueAngle / 360.0), saturation: 0.0, brightness: 0.0, opacity: 1.0)
