Figure 7 – Surfc on X-ray CT brain scanThe contour3 function creates a three-dimensional contour plot of a surface defined on a rectangulargrid (Figure 8.). For example:>> contour3 (brain_scan); figure(gcf)Figure 8. – Contour3 on X-ray CT brain scan3-D Lit Surface Plot (Surface plot with colormap-based lighting, surfl function) displays a shadedsurface based on a combination of ambient, diffuse, and specular lighting models (Figure 9.). Forexample:> > surfl (brain_scan); figure(gcf)Figure 9. - 3D Lit Surface Plot of X-ray CT brain scanThe 3-D Ribbon Graph of Matrix displays a matrix by graphing the columns as segmented strips(Figure 10.).

FILTER VISSUALIZATION TOOL (FVTool )Filter Visualization Tool (FVTool) computes the magnitude response of the <strong>digital</strong> filterdefined with numerator, b and denominator, a. By <strong>using</strong> FVTool we can display the phase response,group delay response, impulse response, step response, pole/zero plot, filter coefficients and round-offnoise power spectrum.(Figures: 11, 12, 13, 14, 15, 16 and 17).Figure 11.
