Convert Python to Matlab

Convert a 300 line simple Python code into Matlab in 2 days for $30 

Snippet of the code below:

from math import *
import numpy as np
import matplotlib.pyplot as plt
#Prandtl-Meyer expansion angle function:
def nu(M,y):
return sqrt((y+1)/(y-1))*atan(sqrt((y-1)*(M**2-1)/(y+1)))-atan(sqrt(M**2-1))
#Prandtl-Meyer Expansion angle for numeric extraction of Mach number
def nu2(M,nu,y):
return sqrt((y+1)/(y-1))*atan(sqrt((y-1)*(M**2-1)/(y+1)))-atan(sqrt(M**2-1))-nu
