through the loop. A while loop executes a block of code an unknown number of times. Termi-nation is controlled by a logical expression, which evaluates to true or false. Here is the simplest while loop for our fixed point iteration. x = 3 while x ~= sqrt(1+x) x = sqrt(1+x) end This produces the same 32 lines of output as the for loop. However ...
Within a method, we can alter the flow of control using either conditionals or loops. The loop statements while, do-while, and for. allow us execute a statement(s) over and over. Like a conditional, a loop is controlled by a boolean expression that determines how many times the statement is executed. E.g.,
15 gru 2022 · There is no 1-to-1 correspondence to the C++ do while loop in MATLAB. Your best option is to use a while loop. The difference is that while loops check the condition at the beginning of the loop while do while loops check the condition at the end of the loop.

2. while loops Create and run a script file with the following commands to see an example of how a while loop works. This script asks for a positive number a as input and estimates √ a using Newton’s Method. Newton’s Method applied to the function f(x) = x2 −a produces a sequence of numbers x1,x2,x3,...that converges to a root of f.
There two types of iterative programming that will be introduced: “for” loops, the exact number of repetitions are set by the programmer. “while” loops, the programmer sets a condition and the code repeats as long as it is true. This lesson will discuss “while” loops. Lab 08B discussed “for” loops.
function [c]=ebyesquwhile(a) len=length(a); ii=1; while ii<=len c(ii)=a(ii)^2; ii=ii+1; end. For a while loop, the index was initialized before the while loop began. The loop compares ii and len, finds that the statement is indeed true, so it calculates c and increments the index by one.
