<p>I have attached a <i>Mathematica</i> Notebook which essentially
accomplishes the same thing we did in class today. It requires
some sophisticated knowledge of how Mathematica stores data
objects, but now that I've done that for you it should be pretty
easy to get <i>Mathematica </i>to fit your data.</p>
<p>There are a couple of things to note.</p>
<p>1. In the first line I have it pointing to a file on my
computer. I had to specify the complete path. You have to modify
this to point to where your data is located.</p>
<p><br>
</p>
<p>2. The FindFit function gives you the option to specify the
starting quess for each of the parameters (a1, x1, etc). You may
have to change these values to get FindFit to locate your peaks
properly.</p>
<p><br>
3. I have to create the fitted function to a list of points so I
could display it alongside the raw data. <br>
</p>

</p>
<p>Please let me know if you have any questions.<br>
