For example, if the vector length is 10000 bits so we repeat the calculation (of any task) until 10000 than we stop and exit. While loop inside another while loop . As we know, do while in Matlab is a simple loop that is used to evaluate the program at least once. Here is an example of how to calculate the factorial of a number using a while loop. The following example script creates a vector containing the areas of circles with radii 1 through 4 using a while loop. otherwise an infinite loop may occur. 1. However ... condition of while to true and place the conditional expression inside the loop. Open example model ex_while_loop_SL. Note that "condition" must change inside the loop! The MATLAB while loop is similar to a do...while loop in other programming languages, such as C and C++. It is possible to never execute the while loop body since the while loop logical expression test is performed first. while statements, loop as long as the condition remains true. Its initial value is the machine epsilon, the distance from 1.0 to the next largest floating-point number on your machine. The execution of a group of statements in the loop is repeated until the expression is true. Otherwise, the expression is false. Example Code. syntax: condition = true; The basic syntax of a while loop is: while condition % do some work. It'll be explained to you in the next lesson. Learn more about while loop, nested loops Example Code Description We will perform the same example we used for explaining for loop but now using the while loop. Therefore, the simplest method to execute the program is to start the program with a while loop that has the true statement and reevaluate the given condition until the loop does not end. While Loop Statements. Example 1 - Simple while Statement. dr.dcd.h CS 101 /SJC 5th Edition 4 while Loop There are two types of while loop while loop (or called repeat until loop) do-while loop (MATLAB didn’t support this) Programming a while loop structure in MATLAB includes three components: the condition/expression, the repeated code block, and a termination statement. The syntax of a while loop in MATLAB is as following: while end The while loop repeatedly executes a program statement(s) as long as the expression remains true. If we have a long vector that we don't know its length, and we want use while loop to repeat the task than stop and exit from the loop when the vector length is at its end. Counting Using while Loops The MATLAB program of Figure 2a shows one way of displaying the numbers from one to ten using a while loop. One method for creating a while loop is to use a While Iterator Subsystem block from the Simulink > Ports and Subsystems library. end. Factorial Example. Its calculation demonstrates while loops. The variable eps is a tolerance used to determine such things as near singularity and rank. An expression is true when the result is nonempty and contains all nonzero elements (logical or real numeric). If you have questions about plotting, see the tutorial on plotting in matlab. Modeling Pattern for While Loop: While Iterator Subsystem block. Syntax of do while in Matlab. count = count + 1; Examples. Creating a While Loop.
