eigenvalues = np.linalg.eigvals(matrix)

matrix_1 = [[3/4,1/4],[1/4,1/4]]
matrix_2 = [[0,1/4],[1/4,1/4]]
print("Is matrix [[3/4,1/4],[1/4,1/4]] positive semidefinite?")

I am attaching the snippet of error messages

`Error: the output of your function isn't the right type.`

How ever if I run this code in Google colab I am getting output as

```
True
Is matrix [[0,1/4],[1/4,1/4]] positive semidefinite?
False```
```
