SQUARE_GRID
Grid of Points Inside a Square in 2D


SQUARE_GRID, a MATLAB library which generates a grid of points over the interior of a square in 2D.

The 2D square is the set of points (X(1),X(2)) such that:

         A(I) <= X(I) <= B(I)
       

For each dimension I, a set of parameters is input:

The centering options allow the user to control the centering of the equally spaced points. This is easiest to illustrate if we look at a 1 dimensional case and assume A = 0 and B = 1. Then, using NS = 4, the centering options will produce 4 equally spaced points as follows:
