Matlab While loop help I'm doing a random walk problem and i need to make it so that when the walker goes over a certain position it gets reflected back onto the center (position=0). For this I'm trying to use while loops but they seem to get stuck. The program works fine until it reaches one of its limits (-10 or 10) then the while loops are supposed to prevent the position from going further and instead send the position...
C Programming Can someone please explain me while the following (c) code prints out 6? for (i=1; x<=5; i++); printf ("%d",i); i=1 initializes the the loop, it is being tested whether it is <= 5 or not. This statement is true, so it goes into the loop and prints 1. After that, i++, means 1+1=2, i=2. This statement is being tested and it is true, we go into the loop and print 2. Then i=3, true, loop prints 3 -->...

MATLAB ONLY!! PLEASE WRITE IN COMPUTER SO I CAN COPY PASTE!!! ANSWER COMPLETELY, USE FOR LOOPS. THE PROGRAM TO BE MODIFIED IS THE NEXT ONE: clc clear % Approximate the value of e ^ x using the Taylor Series x = input( 'Enter the value of x for e^x. x = ' ); t = input( 'Enter the amount of desired terms. t = ' ); i = 1; e_taylor = 0; % initializing the variable for the accumulator while...
QUESTION 1 Which statement results in the value false? The value of count is 0; limit is 10. (count != 0)&&(limit < 20) (count == 0)&&(limit < 20) (count != 0)||(limit < 20) (count == 0)&&(limit < 20) 10 points QUESTION 2 If this code fragment were executed in an otherwise correct and complete program, what would the output be? int a = 3, b = 2, c = 5 if (a > b) a = 4; if (...
Question 1: 1. Figure out what the following MATLAB code does (Notice that R n = 500 for jay - 1:4 ifjoy > 1;oldtime = time; end M rand(n); t cputime; forrep -1:5 R chol(A): en time = cputime-t; if jay > 1; ratio - time/oldtime, end en If you put these instructions into a file named, say, zap.m, you can run the program by typing zap from the MATLAB command line. The functions randn, cputime, and chol are built-in...
True or False: Python programs require two or more modules. 1. 2. The keyword while means the same thing as While in Python. 3. In Python, _MyVar15 is a valid variable name. 4. To make your program more secure, use obscure variable names such as xz14dEE 5. Indenting code that should be executed when an if statement evaluates as true makes your program easier to read, but the indentation is not necessary. 6. A dictionary object contains zero or more...
