Hi,

I have created a recursive function for 2*2 matrix multiplication as part of assignment but i am facing some issue while returning the final output. Can some one please help me please.

Function created:

A = [[1,1],[1,0]]

def square_matrix_power(a,n):

if n==1:

```
return a
```

else:

```
B = [[(A[0][0]*a[0][0]+A[0][1]*a[1][0]),(A[0][0]*a[0][1]+A[0][1]*a[1][1])],[(A[1][0]*a[0][0]+A[1][1]*a[1][0]),(A[1][0]*a[0][1]+A[1][1]*a[1][1])]]
print(B)
square_matrix_power(B,n-1)
```

test run results for

- print(square_matrix_power(A,1))

[[1, 1], [1, 0]]**------ Working as expected** - print(square_matrix_power(A,3))

[[2, 1], [1, 1]]**----- properly multiplied in 1st loop for A^2**

[[3, 2], [2, 1]]**------ Properly multiplied in 2nd loop for A^3**

None**------- Returned value, not worked as expected**

I din’t know why value None returning finally even after properly multiplied in loops…
