@Nehad: do you see how the function name is underlined with a wavy orange line? Do not ignore these mlint warnings: right-click on the warning and see what the message tells you. Most likely that will help you solve your problem.

Hi @Nehad,
The error message you are encountering typically happens when MATLAB can't find the function you're trying to call. Here are few reasons this could happen:
1. Ensure that the function is saved in a file with the exact same name as the function. MATLAB requires that the filename match the function name exactly, including case sensitivity.
For Example: If the function name is "LUCrouts1A" then file name should be "LUCrouts1A.m".
2. Check that the folder containing the function is in the current working directory or is added to the MATLAB path if not.
Please let me know if this resolves the issue.

You can use the addpath function to add any folder to MATLAB search path, and then use savepath to make the changes permanent.
