I have make a script where I import 3 .dat files in a function. like "function myscript('file1.dat','file2.dat','file3.dat')". In the end of my script I make a plot of all of them where I would like to label these filenames (without the .dat). Right now, I how to manually write legend(file1,file2,file3).

Now it is my turn to ask what do you mean? This is how I have coded it and it works this way (which is what I define as valid). What is wrong with the way I write it?

You cannot insert values in the defintion of the headline of a Matlab function. This is not valid Matlab syntax. Therefore we have to guess, what it should do. Perhaps you mean:

function myscript(file1, file2, file3)
...

and call this from e.g. the command line like:

myscript('file1.dat','file2.dat','file3.dat')

(without "function"). Or is the number of files variable?

Please read the "Getting Started" chapters of the documentation to see how to define a function. Without knowing the absolute basics, a discussion in the forum is very time-consuming for you - and for the readers.

Hi, I don't understand how this helps me, can you explain in more depth?

fileparts helps you extract just the filename part of a file path, eliminating the directory and extension.

sprintf helps you put together a string from components, such as a filename and a number that can be dynamically rather than statically included and can be used in a legend.
