Matrix Class

This is a Python implementation of a Matrix class. It supports basic matrix operations such as addition, subtraction, multiplication, and exponentiation. It also has additional methods such as transpose, rowswap, and rowmult that can be used to perform additional matrix operations.

Usage

• Create a matrix by passing a 2-dimensional list of numbers as the argument to the Matrix class
• Use the +, -, * and ** operators to perform addition, subtraction, multiplication and exponentiation respectively.
• Use the transpose, rowswap, and rowmult methods for additional matrix operations.
• The matrix elements are accessible using the [row, col] notation

Note

• The __getitem__ and __setitem__ methods are used to access and set the matrix elements respectively.
• The __str__ method returns a string representation of the matrix in the form of a list of lists.
• The __eq__ method checks if two matrices are equal by comparing their elements.
• The copy method returns a new instance of the matrix with the same elements.
• The __pow__ method raises the matrix to the given power and returns the result.
• The inverse method returns the inverse of the matrix.
