Hi there, I would like to fit the data read in by 'stem' to myfun which is a modelled function in a different script which changes the variable named dp? Thanks

"... myfun which is a modelled function in a different script "
Have to save myfun as an m-file; functions in scripts are local within the script and thus aren't visible outside the script.

If the function you are referring (myfun) is defined in a script, then it is going to be a local function and cannot be accessed outside the script. In that case, as dpb pointed out you may have to save myfun as an m-file and add it to the MATLAB path.
Also, make sure you are passing the argument as function handle in nlintfit function. Please find the documentation for the nlintfit function.
