Class Matrix can add, sub, mul matrix.

With Matrix a, b, c, d and e

a = [[1, 2, 3], [4, 5, 6]]

b = [[10, 11], [20, 21], [30, 31]]

c = [[-23, 3, 8], [-13, 17, -21]]

d = [[32, 17], [-3, 11]]

e = [[9, 8, 7], [6, 5, 4]]

a.dim() = (2, 3)

b.dim() = (3, 2)

c.dim() = (2, 3)

d.dim() = (2, 2)

e.dim() = (2, 3)

a + c = [[-22, 5, 11], [-9, 22, -15]]

a - c = [[24, -1, -5], [17, -12, 27]]

a + 2 = [[3, 4, 5], [6, 7, 8]]

2 + a = [[3, 4, 5], [6, 7, 8]]

a - 3 = [[-2, -1, 0], [1, 2, 3]]

3 - a = [[-2, -1, 0], [1, 2, 3]]

a * 2 = [[2, 4, 6], [8, 10, 12]]

2 * a = [[2, 4, 6], [8, 10, 12]]

a * c = [[-23, 6, 24], [-52, 85, -126]]

e *= 3 : [[27, 24, 21], [18, 15, 12]]

a @ b = [[140, 146], [320, 335]]

b @ a = [[54, 75, 96], [104, 145, 186], [154, 215, 276]]

a @ b + d = [[172, 163], [317, 346]]

a @ b + c @ b = [[210, 204], [-100, -102]]

a += c : [[-22, 5, 11], [-9, 22, -15]]

a -= c : [[1, 2, 3], [4, 5, 6]]

a += 2 : [[3, 4, 5], [6, 7, 8]]

a += -2 : [[1, 2, 3], [4, 5, 6]]
