```The provided Python code demonstrates the computation and examination of eigenvalues and eigenvectors of a matrix using the `numpy.linalg` module. A step-by-step explanation of the code is as follows:

1. **Importing Libraries**: 
   - `from numpy import *` imports various functions and classes from NumPy under the `numpy` alias.
   - `from scipy import *` imports various functions and classes from SciPy under the `scipy` alias.

2. **Creating a Matrix**:
   - The code creates a 2x2 matrix `A` with the following values:
     ```python
     A = array([[1, 2], [3, 4]])

3. Computing Eigenvalues and Eigenvectors:

   • It calls linalg.eig(A) to compute the eigenvalues w and eigenvectors v of matrix A.
   • Eigenvalues are the values along the main diagonal of the diagonalized matrix, and eigenvectors are the corresponding columns.

4. Printing Eigenvalues and Eigenvectors:

   • The code prints the eigenvalues w and eigenvectors v using the print function.

5. Checking Orthonormality:

   • It checks if the eigenvectors are orthonormal (i.e., their norms are equal to 1). It uses linalg.norm(v, axis=0) to compute the norms of each row in v (each row represents an eigenvector) and compares them to 1 using allclose(linalg.norm(v, axis=0), 1).
   • Orthonormal eigenvectors are important for many applications, ensuring that they form a basis for the vector space.

This code effectively computes and investigates the eigenvalues and eigenvectors of a matrix. Eigenvalues and eigenvectors are crucial in various scientific and engineering domains, such as linear algebra, quantum mechanics, and signal processing.
