A small independent package for working with matrixes, written purely in Swift 4. One of the goals of this package is to be buldable for Linux environment as well, thus the package does not depend on other frameworks like Accelerate and so on.
import SwiftMatrix
// Init
let matrix = SwiftMatrix([[0, 0], [2, 3]])
let matrix2 = SwiftMatrix([[0.8, 1.2], [2.1, 3.3]], dimensions: MatrixDimensions(rows: 2, columns: 2))!
// Sum of values
let sum = matrix.sum()
// Directional sum
let dSum = matrix.sum(to: .rows)
// Logarithm
let log = matrix.log()
// Dot product
let dot = matrix.dotProduct(with: matrix2)
// Operators with numbers (Double)
let add = matrix + 2.2
let sub = matrix - 1.1
let mul = matrix * 1.5
let inverted = matrix.invertSign()
// Operators with matrixes
let addM = matrix + matrix2
let subM = matrix - matrix2
let mulM = matrix * matrix2
let divM = matrix / matrix2
// Equation
let equals = matrix == matrix2
// and so on ...MIT License
