scatplot 1.0

% Draws a scatter plot with a colorscale% representing the data density computed% using three methods%% INPUT VARIABLES:% x,y - are the data points% method - is the method used to calculate data densities:% 'circles' - uses circles with a determined area% centered at each data point% 'squares' - uses squares with a determined area% centered at each data point% 'voronoi' - uses voronoi cells to determin data densities% default method is 'voronoi'% radius - is the radius used for the circles or squares% used to calculate the data densities if% (Note: only used in methods 'circles' and 'squares'% default radius is sqrt((range(x)/30)^2 + (range(y)/30)^2)% N - is the size of the square mesh (N x N) used to% filter and calculate contours% default is 100% n - is the number of coeficients used in the 2-D% running mean filter% default is 5% (Note: if n is length(2), n(2) is tjhe number of% of times the filter is applied)% po - plot options:% 0 - No plot% 1 - plots only colored data points (filtered)% 2 - plots colored data points and contours (filtered)% 3 - plots only colored data points (unfiltered)% 4 - plots colored data points and contours (unfiltered)% default is 1% ms - uses this marker size for filled circles% default is 4%% OUTPUT VARIABLE:% out - structure array that contains the following fields:% dd - unfiltered data densities at (x,y)% ddf - filtered data densities at (x,y)% radius - area used in 'circles' and 'squares'% methods to calculate densities% xi - x coordenates for zi matrix% yi - y coordenates for zi matrix% zi - unfiltered data densities at (xi,yi)% zif - filtered data densities at (xi,yi)% [c,h] = contour matrix C as described in% CONTOURC and a handle H to a contourgroup object% hs = scatter points handles
