title: how do i translate this python code to matlab script?
body: <p>I have been trying to convert this python code to Matlab script - but I could really use some help. I am rather new to the programming world as I don't have knowledge of the different commands.</p>
  <p><a href="https://i.stack.imgur.com/bm8sq.png" rel="nofollow noreferrer">python code</a></p>
  <p>I have tried to convert word for word - but I failed desperately :(</p>
  <pre><code>def ranking(A):
       import numpy as np
       from mat1120lib import null
  
   if (A.shape[0] == A.shape[1] and len(A.shape) == 2):
       n = A.shape[0]
   else:
       n=0
       print &quot;A is not a square matrix,aborting!&quot;
       import sys
       sys.exit(1)
   tol = 1e-12
   for i in range(n);
       if (np.sum(A.T[i])-)&gt;tol:
           print &quot;A is not a stochastic matrix, aborting!&quot;
           import sys
           sys.exit(1)
   S=1/float(n) * np.ones((n,n))
   m=0.15
   M=(1-m)*A + m*S
   n=null(M-np.eye(n))
   return n/np.sum(n)
