title: Matlab density plot, Heat map, Matlab
body: <p>x1 and y1 are two array of same length
  scatter (x1,y1); gives the scatterplot of the datas I have</p>
  
  <p>Since there is a highly dense area and low density region in my graph. I would want to have a color Heatmap of the scatterplot.</p>
  
  <p>Is it possible in Matlab.If possible than How.</p>
  
  <p>Thanks in advance</p>
