Change to Text Colour to "RED" after a Logical statement is True and the "Return" Function NOT Terminating

Hi All,

Can you provide advice on the following Im trying to change the output text to "RED" if the second condition is met within my workspace?

Also I have several functions within the script calling several "Return" functions, how do I terminate the TOTAL script after the first return? It seems ALL second condition "Return" functions still run when the code should terminate after the first?

Many thanks.

if cableSpare > 0.2 
    fprintf('\nThe Ampacity for the Cable(s) or Conductors has the following Parameters:\n');
else 
    fprintf('\nRevise Cable Size to Meet Minimum Requirements for Ampacity;\n');
    return
end

fprintf(2, '\nRevise Cable Size to Meet Minimum Requirements for Ampacity;\n');  %notice the 2

The color does not show up here, but does show up in the command window.

Use error to terminate without the cooperation of the outer layers.

Note that code can typically use try, catch to notice that an error has occured and handle it smoothly.

It used to be the case that running out of memory was a condition that could not be caught, so to be sure of terminating code, one way used to be to deliberately request more memory than is possible to allocate. But these days it is possible to catch this error as well.

You can try using cprintf() from the File Exchange.

cableSpare = [0.1 0.3];

for k = 1:numel(cableSpare)
    if cableSpare(k) > 0.2 
        fprintf('\nThe Ampacity for the Cable(s) or Conductors has the following Parameters:\n');
    else 
        cprintf('red','\nRevise Cable Size to Meet Minimum Requirements for Ampacity;\n');
    end
end

It's hard to say why your return is behaving as it is without seeing how the whole thing is written. It should return to the calling function, so if this is part of a function that's called elsewhere, then the calling function/script doesn't stop.
