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: .

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.
