Rewrite the function to use a single for Loop. The one-loop implementation and the two-loop implementation shall return the same 2darray. Sample: if X = np.array([[2, 3, 5], [4, 5, 6]]); Y = np.array([[4, 5, 6], [2, 3, 5], [3, 4, 5]]), then euclid_dist(X, Y) returns array([[3., 0, 1.414], [0, 3., 1.732]]). in python program it will return array([[3., 0, 1.414], [0, 3., 1.732]]).

Answer #1

import numpy as np
def sample(x,y):
return np.sqrt(sum([(a - b) ** 2 for a, b in zip(x, y)]))
X = np.array([[2, 3, 5], [4, 5, 6]])
Y = np.array([[4, 5, 6], [2, 3, 5], [3, 4, 5]])
out1= map(sample,[X[0],X[0],X[0]],Y)
out2= map(sample,[X[1],X[1],X[1]],Y)
out=[list(out1),list(out2)]
print(out)

Curve-Fit Function USING MATLAB Using the top-down design approach, develop a MATLAB function A8P2RAlastname.m that reads data from a file and performs regression analysis using polyfit and polyval. The function shall have the following features: The input arguments shall include the file name (string), a vector of integers for the degrees of polynomial fits to be determined, and an optional plot type specifier (‘m’ for multiple plots, ‘s’ for a single plot - default). The data files will be text...

Write a function in c using #include <stdio.h> that takes a one-dimensional integer array and returns the index of the first occurance of the smallest value in the array. Your function must be able to process all the elements in the array. Create a function prototype and function definition (after the main function). Your main function should declare a 100 element integer array. Prompt the user for the number of integers to enter and then prompt the user for each...

(2nd Problem) From Chapter 15 on page 1080, do problem #5. Recursive function that computes the same of values in an array. To test this function in the main, create the following array: int a[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}; #15. Write a recursive function that finds and returns the sum of the elements of an int array. Also, write a program to test your function.

IN C++ AS SIMPLE AS POSSIBLE ______ Re-write the given function, printSeriesSquareFifth,  to use a while loop (instead of for). • The function takes a single integer n as a parameter • The function prints a series between 1 and that parameter, and also prints its result • The result is calculated by summing the numbers between 1 and n (inclusive). If a number is divisible by 5, its square gets added to the result instead. • The function does not...

How can this PHP code be changed to use a parameter to the function that you would then pass $students in? (instead of using a global). Also, can you show how to use a loop to handle any length of array? (instead of an array that is 3 elements). <?php $students = array(     array('FName'=>'Jane', 'LName'=>'Doe', 'ClassScore'=>90),     array('FName'=>'Bob', 'LName'=>'Joe', 'ClassScore'=>50),     array('FName'=>'John', 'LName'=>'Doe', 'ClassScore'=>20)     );     //1.

Questions: 1. Create a VB.NET Console Application that defines a function Smallest and calls this function from the main program. The function Smallest takes three parameters, all of the Integer data type, and returns the value of the smallest among the three parameters. The main program should (1) Prompt a message (using Console.WriteLine) to ask the user to input three integers. (2) Call the built-in function Console.ReadLine() three times to get the user’s input. (3) Convert the user’s input from...
