Question

Problem 4 (7 points): What is the output (printed to command prompt) of the following code (Exam2Prob4.m)? DO NOT USE MATLAB for solving this problem. ZERO CREDIT if all steps are not shown. You should explain the output of each code as if you are executing the code. (answer 2 points; process, with each step - 8 points) Exam2 Prob4.m clc; clear; close all; p=4; q = 3; r5; (x, y] = user Defined (p, q, r); fprintf('x- $d, y=%d',x,y); user Defined.m function [a,b] =user Defined(u, v,W) a = u*v + VW + u*w; b = sqrt (u 2+v+2) -w; end

Answer 1

Answer:

temp 2 3 4 % cleaning command window and clearing all variables from current workspace clc; clear; close all; Сл 6 7 9 10 11 12 13 14 15 16 17 18 19 20 % storing values in the variables p = 4; q = 3; r = 5; [x,y] = userDefined(p,q,r); % here calling the function userDefined (4,3,5) and the returned values are stored in x,y variables function [a,b] = userDefined(u,v,w) % 4,3,5 will be mapped to u,v,w respectively so u=4, v=3, w=5 and x = a, y=b a = u*v + v*W + u*w; a = 4*3 + 3*5 + 4*5; a = 12 + 15 + 20; a = 47 b = sqrt(u^2+v^2)-W; b = sqrt(4^2+3^2)-5; b = sqrt(16+9)-5; b = sqrt(25) -5; b = 5 - 5; b = 0; end so after this function x and y values are a and b that means x = a = 47 and y = b = 0 26 27 28 29 30 31 fprintf(" x= %d, y= %d',x,y); printing x and values to command window. Output is : x= 47, y= o
