However ... condition of while to true and place the conditional expression inside the loop. Modeling Pattern for While Loop: While Iterator Subsystem block. If you have questions about plotting, see the tutorial on plotting in matlab. The execution of a group of statements in the loop is repeated until the expression is true. Learn more about while loop, nested loops It'll be explained to you in the next lesson. while statements, loop as long as the condition remains true. 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. Matlab grants the user to use the various kinds of loops in Matlab programming that are used to handle different looping requirements that involve: while loops, for loops, and nested loops. 1. Programming a while loop structure in MATLAB includes three components: the condition/expression, the repeated code block, and a termination statement. Example Code Description Creating a While Loop. Examples. Its calculation demonstrates while loops. While loop inside another while loop . Example 1 - Simple while Statement. 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. 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) Its initial value is the machine epsilon, the distance from 1.0 to the next largest floating-point number on your machine. The variable eps is a tolerance used to determine such things as near singularity and rank. One method for creating a while loop is to use a While Iterator Subsystem block from the Simulink > Ports and Subsystems library. The following example script creates a vector containing the areas of circles with radii 1 through 4 using a while loop. syntax: condition = true; Open example model ex_while_loop_SL. Here is an example of how to calculate the factorial of a number using a while loop. Syntax of do while in Matlab. otherwise an infinite loop may occur. 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. The MATLAB while loop is similar to a do...while loop in other programming languages, such as C and C++. For example, if the vector length is 10000 bits so we repeat the calculation (of any task) until 10000 than we stop and exit. Example Code. Otherwise, the expression is false. end. We will perform the same example we used for explaining for loop but now using the while loop. count = count + 1; An expression is true when the result is nonempty and contains all nonzero elements (logical or real numeric). It is possible to never execute the while loop body since the while loop logical expression test is performed first. 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. Note that "condition" must change inside the loop! As we know, do while in Matlab is a simple loop that is used to evaluate the program at least once. While Loop Statements. Factorial Example.
