Matrix operations and methods

matrixcea

matrixcea is a simple Python library for performing matrix operations.
It supports basic linear algebra operations, including addition, subtraction, multiplication, determinant, transpose, reshaping, and even negative powers (using matrix inverse).

Features

• Create matrices from lists of lists or single row.
• Matrix addition, subtraction, scalar multiplication, and matrix multiplication.
• Transpose, flatten, and reshape matrices.
• Determinant calculation for square matrices.
• Check for square, identity, symmetric, or zero matrices.
• Raise a matrix to a positive or negative integer power.
• Compute matrix inverse (for square, non-singular matrices).
• Element-wise division by a scalar.
• Operator overloading for Pythonic syntax:

  A + B
  A - B
  A @ B      # matrix multiplication
  A * 3      # scalar multiplication
  3 * A      # scalar multiplication
  A ** -1    # matrix inverse
  A ** 3     # matrix power
  

Usage example:

from matxxforgex import matrix

Create matrices

A = matrix([[1, 2], [3, 4]])
B = matrix([[5, 6], [7, 8]])

Arithmetic operations

C = A + B
D = A - B
E = A @ B
F = A * 2
G = 2 * A
H = A / 2

Properties

print(A.is_square())    # True
print(A.is_identity())  # False
print(A.is_symmetric()) # False
print(A.is_zero())      # False

Advanced

det = A.determinant()
A_inv = A.inverse()
A_pow = A ** 3
A_neg = A ** -1
A_T = A.transpose()
flat = A.flatten()
reshaped = A.reshape(1, 4)
