Symentic Matrix Using Python

What is Symmetric Matrix?

A=[1 2]

     [2 1] is a Square Matrix . When We Modify The Given Matrix Row Into Column And Column Into Row. if Modified and Original Matrix Array Are Same It Known As Symmetric Matrix.

If A=A'

    A=[1 2]                        A'=[1 2]

         [2 1]   is Equal To       [2  1]

Other Wise Given Matrix is Non Symmetric.

The Follow Simple Python Code For Find The Given Array Is Symmetric or Not.

arr=[[1,2],[2,1]]

n=len(arr[0])

m=len(arr)

isTrue=1

for i in range(0,n):

    for j in range(0,m):

        if(arr[i][j]!=arr[j][i]):

            isTrue=0

            break;

print(isTrue) 

output:

1
