create a while loop in matlab

In MATLAB, you can create a while loop using the following syntax:

main.m
while condition
    % code to be executed while the condition is true
end
74 chars
4 lines

The loop will continue to execute the code between while and end while the condition is true. Once the condition evaluates to false, the loop will exit and the program will continue to execute the code after the loop.

Here's an example of using a while loop to calculate the sum of the first 100 positive integers:

main.m
% initialize variables
i = 1;
sum = 0;

% calculate sum of first 100 positive integers
while i <= 100
    sum = sum + i;
    i = i + 1;
end

% display the sum
disp(sum);

In this example, the condition is i <= 100, which will evaluate to true for the first 100 iterations of the loop. The loop will add the current value of i to the sum variable, increment i by 1, and then continue until i reaches 101, at which point the loop will exit and the program will display the final value of sum.
