Compute a Quadrature Rule for the Unit Quarter Disk

DISK01_QUARTER_RULE is a MATLAB program which demonstrates how to compute a quadrature rule of a particular precision to estimate integrals over the interior of the unit quarter disk in 2D.

The unit quarter disk in 2D is the set of points (X,Y) such that 0 <= X, 0 <= Y, and X^2+Y^2 <= 1.

The program sets up the nonlinear equations that characterize the points and weights of the rule, and then calls MATLAB's fsolve() function to solve the nonlinear system.
