Use Histogram and Parzen Window for 2D dataset to estimate Kenrnel Density Estimation and Plot Figure 3D for Pattern Recognition
add dataset seprate x,y
estimaate Histogram and Parzen WIndow with (start point and end point) , (Bin width), (H) , (P_W) and Draw It
Next Estimate Kernel Density and Plot 3D figure with (x , y , KDE)
