Matrix

Revolutionary python class. It can all of the major matrix functions, including addition, subtraction, multiplication, inverse, determinant, and it can solve a system of equations.

Examples

a = Matrix([[1,2],[3,4]])
b = Matrix([[4,3],[2,1]])
#Sets matrices a,b

Printing

print(a)
>>> [1, 2]
    [3, 4]
print(~a)
>>> [-2.0,1.0]
    [1.5,-0.5]

Inverse

g = ~a
print(a * g)
>>> [1, 0]
    [0, 1]

Determinant

d = abs(b)
print(d)
>>> -2

Addition, Subtraction

c = a + b
d = a - b

Exponentiation

c = a ** 3
print(c)
>>> [37, 54]
    [81, 118]

Multiplication

print(a * 3)
>>> [3, 6]
    [9, 12]
print(a * b)
>>> [8, 5]
    [20, 13]

Division

    print(a / b) #a * ~b
    >>> [1.5, -2.5]
        [2.5, -3.5]

Solving Systems

g = Matrix([[1,3,7],[2,4,10]])
print(g.solve())
>>> (1.0,2.0) #x = 1.0, y = 2.0
