Thread Subject: newbie's question

Hi

I am not familiar with M file.
How to group some similar or useful M-file functions together? In
other programming languages, users usually compile them into a
library.

Any suggestions are very welcome. Thank you very much in advance.

ML is interpreted, not compiled so don't need to do anything but put the
collection of m-files in a directory in the working path.

Once debugged, if speed is an issue, then one can create mex files which
are compiled callable from ML.

But, if I put them in a directory, I might have less chance to use
them again.

You need to add the directory in the search path in order to use them everywhere.

??? No clue what you're thinking in reality--wherever they are they're
in _a_ directory. Whether they're on the working search path is the key
to accessibility in ML.

Read the section in programming w/ m-files on how search order is
resolved...

thank you. In fact, I had set the Path.
Is it better to name M-file function a prefix like 'fun_XXX" to
distinguish with main M file?

You can name m-files however you like.
If fun_XXX makes sense to you, go for it!

However, if you name the function m-file fun_XXX, then
the first line of the function m-file should be something like:

function [x,y,z] = fun_XXX(a,b,c)

thanks.

Read the 'Function Names' section on m-file programming in the "Using
Matlab/Programming" chapter...
