Square Matrices are one of the important Matrices and therefore, we are going to write a python code to check whether the matrix is square or not?

平方矩阵是重要的矩阵之一，因此，我们将编写一个python代码来检查矩阵是否为平方？

## 用于检查方矩阵的Python代码 **(**Python code for checking square matrix**)** ##

# Linear Algebra Learning Sequence
    # Checking Square Matrix
    
    import numpy as np
    
    # Use of np.array() to define rows
    V1 = np.array([45,78,65,99])
    V2 = np.array([68,87,97,48])
    V3 = np.array([74,68,77,48])
    
    print("The Row v1: ",V1)
    print("The Row v2: ",V2)
    print("The Row v3: ",V3)
    
    # Making a Matrix using Vectors
    M = np.vstack([V1,V2,V3])
    
    print("\n\n-----Matrix M---\n", M)
    
    [r,c] = M.shape
    if r == c:
        print("Matrix is square with dim ",r,'x',r )
    else:
        print("Matrix is not square with dim ",r,'x',c )
    
    V1 = np.array([[1,2,3],[2,3,5],[3,6,8],[323,623,823]])
    V2 = np.array([[965,2413,78],[223,356,500],[312,66,78]])
    
    [r2,c2] = V1.shape
    [r3,c3] = V2.shape
    print('\n\n----Matrix A----\n',V1)
    if r2 == c2:
        print("Matrix is square with dim ",r2,'x',r2 )
    else:
        print("Matrix is not square with dim ",r2,'x',c2 )
    
    print('\n\n----Matrix B----\n',V2)
    if r3 == c3:
        print("Matrix is square with dim ",r3,'x',r3 )
    else:
        print("Matrix is not square with dim ",r3,'x',c3 )

**Output:**

**输出：**

The Row v1:  [45 78 65 99]
    The Row v2:  [68 87 97 48]
    The Row v3:  [74 68 77 48]
    
    
    -----Matrix M---
     [[45 78 65 99]
     [68 87 97 48]
     [74 68 77 48]]
    Matrix is not square with dim  3 x 4
    
    
    ----Matrix A----
     [[  1   2   3]
     [  2   3   5]
     [  3   6   8]
     [323 623 823]]
    Matrix is not square with dim  4 x 3
    
    
    ----Matrix B----
     [[ 965 2413   78]
     [ 223  356  500]
     [ 312   66   78]]
    Matrix is square with dim  3 x 3
