Your precious feedbacks are very important for us. If you wish for further examples about the use of the ‘while’ loop, leave your requests in the comment section.ĭo not forget to leave your comments and questions about the ‘while’ loop in Matlab® below.
ConclusionĪs you see in the examples above, while loop is a very useful loop command that can be used in Matlab® programming. So, the value of ‘i’ after the execution of the ‘break’ command, will give the address of element of ‘a’ which has the value of 45.īy using the ‘disp()’ command , we display this value in the command window. So, inside the ‘if-else’ query inside the ‘while’ loop, we stop the loop if the value of the element is 45. In the ‘while’ loop, we want to find the address of the element which has the value of 45. Also, we created a variable ‘i’ which has the value of 1, to build the ‘while’ loop. Take a look at the example below 1 > a= ĭisp() Īt the example above which is executed in the Matlab® command window, we created a vector ‘a’ that has various integers inside it. ‘Break’ is generally used in if-else queries in Matlab® programming. ‘Break’ is a very useful command to halt the all program if the statement is true in Matlab®.

If the element of ‘a’ is bigger than 60, the Matlab® compiler will exit the while loop, then disp() commands will work to show the first element of a which is bigger than 60.
If the element of ‘a’ is smaller than 60, code inside while will increase the value of counter 1. In the ‘while’ command, we question all the elements of vector ‘a’ by typing the counter inside ‘a’. There are starting values of x and y variables, which are 5 and 1. To do it, we assigned a counter ‘y’ which has an initial value of 1. To start the while loop you type while followed by a logical expression that you would like to test every time before entering the loop. Here you can see a very basic example of the use of the while loop in Matlab. In this example about the use of the ‘while’ command, we want to find the first element of vector ‘a’ which is bigger than 60. Take a look at the example below about ‘while’ command in Matlab®. Then you can see the last value of ‘y’ at the command window in the example above in Matlab®. In each loop, we increase the value of ‘x’ for 1. To do this, we used the ‘while’ code that the code inside the loop will work while the condition x>y is true. So, we need to stop the working of code when the values of ‘x’ and ‘y’ are equal. In the ‘while’ loop, we want to increase the value of ‘y’ up to the value of ‘x’. There are starting values of ‘x’ and ‘y’ variables, which are 5 and 1 respectively. Here you can see a very basic example of the use of the ‘while’ loop in Matlab®.

How To Use ‘while’ Loop In Matlab®? > x = 5 The use of the while command in Matlab® to code loops is very easy. Along with the for-end loop, while loop is also a loop programming command in Matlab®.
N=input('Please enter a positive number: ') įprintf('The number you entered was not a positive number.') įprintf('Please enter another number\n') įprintf('%d : number entered = %4.2f | product = %4.Like in other programming languages, you can also code loops in Matlab®. I think that what I need is a way to save the data within the loop but no idea how to save for multiple values. So far what I have can show these statements but only immediately after each input, instead of all together at the end. I'm seriously struggling on one particular section in this question that's asking us to, using a loop, get the user to input positive numbers until the total product reaches 500 and THEN for a table to be in a form similar toġ: number entered =.
