Mulab: a Matlab Toolbox

The {$\mu$}lab Toolbox is free for installation and also probably the most open to modifications (if you have Matlab, for the moment). It shall be ported to octave in the next future, to make it really an open package. Two fundamental blocks, the loading routines and the fminuit engine are the work of G. Allodi (the latter also of F. James, of course)

Here we offer:

• to download the toolbox.
• A primer, for immediate use.
• Mulab tools, a brief description.
• Advanced topics, at a second reading

• Installation (and license) instructions
• Troubleshooting simple problems.
• Changelog, a summary of the new features as they come
• TODO list of future improvements.

• A description of its structure, for maintainers, for those wishing to insert new functions, but also simply for being able to exploit matlab on the muon data.
• Plans for a double fit in Ver. 2.0
• How to add a fit component to the mulab suite
• How to modify the main MULAB GUI window

A few immediate help suggestions

If you are familiar with μSR start having a look at the Mulab Primer.
If you want a reference for all the buttons, inputs and dropdowns of the main mulab (fit) window type

 help mufit_gui

st the matlab command
A brief description of the main tools is in MuSR.MulabTools.

Mulab is a library of directly accessible functions. Being a Matlab Toolbox, Mulab shares the usual help scheme of matlab functions: typing

from the matlab prompt you get some information and hints. If installed correctly

offers the contents, a survey of available functions. If installed in any directory, you can run mulab from that directory and display the contents help by

Remember that in these helps, following Matlab conventions, the function commands are written in uppercase, for highlighting purposes, but all commands are lowercase.

{$\mu$}lab leaves a blank workspace and transfers information among functions by means of a number of global structures. Their catalog is obtained by typing

By typing

in the command window, for instance, you can access the data set loaded by {$\mu$}lab. Note that the global names are uppercase. Being a structure, you can just type MU_DATA to display the first level of fields. You can recursively explore those fields which are themselves structures.
