copilot:summary
🐞 Related Issue
Closes https://github.com/codinasion/codinasion/issues/3937
📋 Explanation of changes
1)Subroutine Definition (matrix_inverse):
-The program defines a subroutine named matrix_inverse that takes a square matrix as input and returns its inverse.
-It first checks if the matrix is square. If not, it throws an error.
-The subroutine uses Gauss-Jordan elimination to find the inverse of the matrix.
2)Matrix Augmentation:
-The input matrix is augmented with an identity matrix to create an augmented matrix.
3)Gauss-Jordan Elimination:
-The program performs Gauss-Jordan elimination to transform the augmented matrix into the form [I | A^(-1)], where I is the identity matrix and A^(-1) is the inverse matrix.
4)Extracting Inverse Matrix:
-The inverse matrix is then extracted from the augmented matrix.
5)Example Usage:
-An example 3x3 matrix is provided, and the matrix_inverse subroutine is called with this matrix.
-The program then prints the resulting inverse matrix.
