how do you add units to a function output in matlab

To add units to a function output in MATLAB, you can attach the units as a string to the end of the output value. This can be achieved by using the num2str() function to convert the value to a string, and concatenating the unit to the end of the string. For example:

main.m
outputValue = 3.14; % Example output value
outputUnit = 'm/s'; % Example output unit
outputString = [num2str(outputValue), ' ', outputUnit]; % Combine value and unit with a space in between
disp(outputString); % Display the output string
238 chars
5 lines

This will produce an output in the form of 3.14 m/s.
