Function file does not work

If I save a function in a file it is not work even I save the function file in the same folder of the code

the error is

'Undefined function 'Crouts1A' for input arguments of type 'double'.'

but if I write the function in the last code it is work.. how can I fix it.

My version Matlab is R2024a

That's weird

can you show the code ?

My guess is a local function in a script, which seems to be a popular mistake these days. But without the code we can only guess.

here is the code

@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.

How can I added to Matla path?

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