					<h3>Introduction to the MATLAB code</h3>

					<p>
						The MATLAB code is contained within the following directories:
					</p>
					<ul>
						<li><code>./state_tomography</code></li>
						<li><code>./state_tomography/private</code></li>
						<li><code>./quantum_logic</code></li>
						<li><code>./quantum_logic/measures</code></li>
						<li><code>./basic_math</code></li>
						<li><code>./util</code></li>
					</ul>
					The function <code>state_tomography.m</code> is the top level tomography program, and the place you should start when looking through this code. Its function call looks like this:
					<blockquote>
						<code>[rho, intensity, fval]=state_tomography(raw_counts, intensities, conf)</code>
					</blockquote>
