How to Use

import Matrix

let A = Matrix(rows: 3, columns: 2,
               data: [1, 2.5,
                      3, 4.5,
                      5, 6]) // A.data = [[1.0, 2.5], [3.0, 4.5], [5.0, 6.0]]
        
let B = Matrix(rows: 2, columns: 2) // B.data = [[1, 0], [0, 1]]
try B.setData([1.0]) // throws MatrixError.wrongDimension -> Needed 4, got 1
try B.setData([7.0, 8,
                9, 10]) // B.data = [[7.0, 8.0], [9.0, 10.0]]
        
let v = Vector(rows: 3)
try v.setData(args: 1, 2, 3.0) // v.data = [[1.0], [2.0]. [3.0]]
        
let AxB = try? A * B // AxB.data = [[29.0,33.0], [61.5, 69.0], [89.0, 100.0]]
