xyz2pd.m

Probability density estimation for a three-dimensional Cartesian point cloud on a user-specified regular grid.

Syntax

            density=xyz2pd(coords,x_range,y_range,z_range,...
                                  x_npts, y_npts, z_npts)

Parameters

       coords  - an N-by-3 array of Cartesian coordinates
       x_range - a two-element vector [xmin xmax] specifying the
                 Cartesian grid extent along the x axis
       y_range - a two-element vector [ymin ymax] specifying the
                 Cartesian grid extent along the y axis
       z_range - a two-element vector [zmin zmax] specifying the
                 Cartesian grid extent along the z axis
       x_npts  - the number of grid points along the x axis
       y_npts  - the number of grid points along the y axis
       z_npts  - the number of grid points along the z axis

Outputs

       density - a three-dimensional array containing the num-
                 ber of points falling into each grid cell
