What does it mean to have an index to scalar variable error? python

Question

import numpy as np

with open(\'matrix.txt\', \'r\') as f:
    x = []
    for line in f:
        x.append(map(int, line.split()))
f.close()

a = array(x)

l, v = eig         


        

Answer 1

exponent is a 1D array. This means that exponent[0] is a scalar, and exponent[0][i] is trying to access it as if it were an array.

Did you mean to say:

L = identity(len(l))
for i in xrange(len(l)):
    L[i][i] = exponent[i]

or even

L = diag(exponent)

?
