Dear Colleagues<br>
<br>
I'm proud to introduce to you a new tool for Matlab, <a
href="http://ifit.mccode.org"><i><b>iFit</b></i></a>.<br>
<b><br>
</b>
<div align="center"><b>iFit version 1.0-RC1, Feb 2011</b><br>
</div>
<blockquote>The <span style="font-style: italic; font-weight:
bold;">iFit</span> library is a set of methods to load, analyze,
plot, fit and optimize models, and export results. <span
style="font-style: italic;">iFit</span> is based on Matlab. It
does not currently include advanced graphical user interfaces
(GUI), and rather focuses on <span style="font-style: italic;">doing
the math right</span>. Any text file can be imported straight
away, and a set of binary files are supported.<br>
<br>
The spirit of the library is to include a single object
definition, with a limited set of methods that provide all the
means to perform the usual data analysis procedures. <br>
</blockquote>
<br>
This is a script-based software that has, in short, the following
capabilities:<br>
<ul>
<li>Load any text formatted file, and a large set of binary format
files (NeXus, EDF...)<br>
</li>
<li>Display object information, including metadata from the
original file<br>
</li>
<li>Plot the object Signal in a simple view for 1D, 2D and 3D
objects</li>
<li>Perform mathematical operations using objects (=-/*)
trigonometric projections integration re-binning...</li>
<li>Fit a parametrized model to the object Signal, which makes use
of the iOptim and iFuncs libraries.<br>
</li>
<li>Save the object into a set of output formats</li>
</ul>
To obtain the package for testing, and read the documentation, refer
to: <br>
<br>
<div align="center"><<a href="http://ifit.mccode.org">http://ifit.mccode.org</a>><br>
</div>
<br>
The documentation explains how to use the package, all based upon
ready-to-try examples.<br>
<br>
Currently, the model fit functions is limited to only the Gaussian.
This will be extended with your help and pressure. This is a product
from the <a
href="http://www.ill.eu/instruments-support/computing-for-science/home/">ILL/CS</a>,
and the concepts in iFit may contribute to the future software
developments in CS (super-Lamp, Mantid, ...).<br>
<br>
<i><b>Disclaimer</b></i>: this is a prototype. It does not include
all the functionalities that <a
href="http://www.ill.eu/instruments-support/computing-for-science/cs-software/all-software/matlab-ill/">MFit/MView/Spec1d</a>
or LAMP have. It does not have the same objective. However, it will
evolve thanks to you (and me) and try to meet the demand... <i>There
will be bugs.</i> Please report back to improve the package for
the benefit of all, and tell me what you think.<br>
