Question

1. Write a function called yLim which takes as input the vectors r and y. This function returns a vector of length 2, which contains the values in y that occur in the positions of the minimum and maximum values of r. That is, x c (100, 13, 1, 20) y c (5 7, 9, 0) y Lim (x, y) [1] 9 5 Since the minimum of is in the 3rd element of z maximum of z (which are 9 and in position, the return value is vector containing the 3rd and first values in y a 5, respectively). is shorter than y, Additionally, the input z is required, and u has a default value of r. If then a message should be issued but the computation is carried out. shorter than r, then the function is erminated and a message issued. You may assume that there is a is minimum and maximum in z and there are no As in either a or y

Explanation / Answer

import numpy as np

def yLim(x, y):
    min = float('Inf')
    max = float('-Inf')
    mini = 0
    maxi = 0
    if len(x)>len(y):
        print "The length of x is greater than y."
        return
    else:
        if len(y)>len(x):
            print "The length of y is greater than x."
        for i in range(len(x)):
            if x[i]>max:
                max = x[i]
                maxi = i
            if x[i]<min:
                min = x[i]
                mini = i
    return y[mini], y[maxi]

x = [100, 13, 1, 20]
y = [5, 7, 9, 0]
ans = yLim(x, y)
print ans[0], ans[1]
