A simple example of a while loop isx = 5;k = 0;while x < 25k = k + 1;y(k) = 3*x;x = 2*x-1;end1-52The loop variable x is initially assigned the value 5, and itkeeps this value until the statement x = 2*x - 1 isencountered the first time. Its value then changes to 9.Before each pass through the loop, x is checked to see ifits value is less than 25. If so, the pass is made. If not, theloop is skipped.
Example of a for LoopWrite a script file to compute the sum of the first15 terms in the series 5k 2 – 2k, k = 1, 2, 3, …,15.total = 0;for k = 1:15endtotal = 5*k^2 - 2*k + total;disp(’The sum for 15 terms is:’)disp(total)The answer is 5960.1-53
