WEDGE_MONTE_CARLO <br> Monte Carlo Integral Estimates over the Unit Wedge in 3D
</h1>
<hr>
<p>
<b>WEDGE_MONTE_CARLO</b>
is a MATLAB library which
uses the Monte Carlo method to estimate the integral of a function
over the interior of the unit wedge in 3D
</p>
<p>
The interior of the unit wedge in 3D is defined by the constraints:
<pre>
0 <= X
0 <= Y
X + Y <= 1
-1 <= Z <= +1
</pre>
