You may note here that as the value of N is decreasing in each iteration, it will always satisfy the condition and hence will continue working infinitely. while statements loop as long as a condition remains true. Let’s understand the flow diagram of a while loop for better clarity. Thereafter, they can also practice various examples available on the web or try to create some simple exercises yourself. '); CheckAns = strcmpi(Ans,{'yes';'no'}); if strcmpi(Ans,'yes') disp('Happy birthday') elseif strcmpi(Ans,'no') disp('Haha loser') end end Infinite loop may occur (Use with caution !) % while loop execution example If you are familiar with other programming languages then you must be aware of loops such as for loop, if loop, while loop, etc. Based on your location, we recommend that you select: . Web browsers do not support MATLAB commands. ALL RIGHTS RESERVED. Hadoop, Data Science, Statistics & others. For students and beginners, however, it does come with a limited-time trial version. Your while condition returns a logical vector, and if any of its components is false the whole thing is false and the loop ends. Is not it simple and yet so powerful? What it means is that the while loop will run till the value of a is less than 20. All 0 to start and enter the loop CheckAns = [0 0 0 0]; while ~sum(CheckAns) Ans = inputdlg('Is this your birthday? An expression is true when the result is nonempty and contains all nonzero elements (logical or real numeric). Syntax: If (condition) My while cycle must work until ALL conditions inside my vectors are satisfied. The end is the keyword which suggested the closure of the loop. Otherwise, the expression is false. If the first expression or condition is true then ‘ if ’ statement executes. Sorry for bothering you for multiple times and thank you for your all help. Now the value of a is 11 which is still less than 20 so the loop runs again. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. Select a Web Site. Accelerating the pace of engineering and science. A line starting with % is the comment in MATLAB, so we can ignore the same. Statements are the actions that would be executed if the condition or expression is true. T_WATERback=ones(1,n_windings)*T_water_hp; T_WIREback=ones(1,n_windings)*(180+273.15); cond_1 = sum(abs(T_WATERfront-T_WATERback)>eps) == length(T_WATERfront). Skip to content. Learn more about while loop, curve lenght . To better understand the syntax, let’s take an example. With the above examples and explanations, I hope the article gave a fair idea of while loop in MATLAB. i = i + 1; An expression is true when the result is nonempty and contains all nonzero elements (logical or real numeric). As per the above syntax, the following is an example of a nested loop in Matlab. While loop repeats the execution of the statements while the condition is true; while (expression) statements(s) end. If the expression is false then else statement executes. Vote. s = s + i; a==c. % while loop execution example Skip to content. Follow 28 views (last 30 days) Roman on 26 Oct 2013. In this section, we shall explain the same ideas in more detail. How would I make a loop that does the loop until one of multiple conditions is met. While Loop if Condition is True. while( a < 20 ) end. Produkte; ... How to define multiple while loop conditions? If you want any sub expression to end the loop, replace '|| again by &&. Choose a web site to get translated content where available and see local events and offers. Statements in the loop that appear after the break statement are not executed. Since you know the row size of the matrix you are working with, one option for the condition in the while statement would be to continue iterating so long as the calculated value of ‘r’ for the next iteration is less than or equal to the row size of the matrix. Syntax. Reload the page to see its updated state. For example: do { srand (time(0)); estrength = rand()%100); srand (time(0)); strength = rand()%100); } while( ) //either strength or estrength is not equal to 100. Find the treasures in MATLAB Central and discover how the community can help you! 1. else b==c. While loop starts and the condition is less than 20. An expression is a condition that needs to be true for the while loop to work. Next line prints the current value of a and after that, the next line is executed. A while loop has mainly three parts that need to be understood. Sign in to comment. https://uk.mathworks.com/matlabcentral/answers/494506-while-loop-multiple-conditions#answer_404424. This can be calculated to give the below result: As we have taken i=5, then i2(i + 1 ) = 52 * 6 = 150 This is what you get in MATLAB: a = 0; for m = 1:5 for n = 1:5 a = a + m + n; … Finally, the loop runs until a attains the value 19 and after that, it stops. Control passes to the statement following the end of that loop. b) Logic of the loop prevents the loop condition from becoming false. It has three parts if statement, else statement and else if statement if-else statement in Matlab. The line a=a+1, adds 1 to a and then the while condition is again checked. So effectively you have to turn your … Otherwise, the expression is false. By continuing to use this website, you consent to our use of cookies. But, it is expected that you know the basic data types in MATLAB. while loop multiple conditions. MATLAB is a scientific programming language that is used a lot for research and academic purposes. Then run the equation: value=c2* (c^2)+c1*c+c0 again with update a or b … Based on the condition provided, a while loop can run for a finite number of times producing finite output or it can go for as long as possible unless stopped manually. while( i < 3 ) while
