How to create a loop so i can compare accuracy of output values?

I need to create a loop so that the process repeats itself until the output value is within a certain accuracy eg 10%

Try this

loopCounter = 1;
maxIterations = 1000000; % or whatever would be the highest you ever expect.
tolerance = 0.001; % Whatever you want.
while loopCounter  < maxIterations && difference1 < tolerance && difference2 < tolerance
    difference1 = abs(yourValue1 - targetValue1);
    difference2 = abs(yourValue2 - targetValue2);
    % Now have code to update yourValues and get new ones.
    yourValue1 = ......
    yourValue2 = ......
    loopCounter = loopCounter + 1; % Increment loop counter
end

Which sections do i replace with my variables?

Also many thanks for your response.

We don't know. Your question is gone so we no longer know what you want to do.

In the future, just start new questions for new questions. Don't obliterate old ones and replace them. For the new question, did you try something like this:

toleranceLevel = 0.1;
difference = inf;
while difference < toleranceLevel 
    % Code to compute new value....
    % Now test the new value
    difference = newValue / referenceValue;
end

For the orignal answer you posted. I'm using your code however an error comes up saying the following "undefined function or variable difference1".

Even though I've changed it and set all prior variables.

I'm quite new to matlab so please bear with me.

Many thanks for your response.

Sorry, we forgot to initialize the differences before the while loop. Do this before the loop

% Initialize differences to infinity;
difference1 = inf;
difference2 = inf;

Thank you. Final question.

How do i get it to show the 2 output values that are being used to compare accuracy at the end?

At the moment it shows a single output value and a graph (which is part for the rest).

[Image Analyst]

How do you want to show them? Maybe with fprintf()? Maybe on a graph with yline()? I have no idea what you want. It's best to start your own question with your own data and code.
