Doug’s MATLAB Video Tutorials

October 23rd, 2009

I like his slow, clear, methodical presentation with great visualizations. It is the first time I have deeply understood some of the volume visualization techniques we have. Sorry, Dr. H, but I really did not understand Div, Grad, Curl and all of that until Patrick explained it later in this series!

• 1 of 9 Definitions for scalar and vector fields.
• 2 of 9 Examples of scalar and vector fields (temperature in a room vs air currents)
• 3 of 9 Displays scatter3 and slice plots.
• 4 of 9 Displays contourslice and isosurface.
• 5 of 9 Making a 3-d plot ‘pretty’ with lighting, shading, interpolation, etc…
• 6 of 9 Displays quiver3 and coneplot
• 7 of 9 Displays and explains streamplot and streamslice
• 8 of 9 Displays and explains streamtubes and streamribbons
• 9 of 9 Unifying example

   Good to hear that people are interested in this. It is quite a commitment of blog space to do this. Should I increase the pace during a series?

   -Thanks!

   Nice topic!

   I’m sure I will learn something useful in this series!

   Certainly! If the videos are already composed, may I suggest posting them to the FEx? Your readers will surely still come for the insightful comments.

   Good stuff Doug, I’d be in favor of a speedier series if there are 9 total, mainly so I don’t forget where the earlier videos left off.

   Hi , I am interested if you can help me on how can I found functions in MATLAB.
   I need to find difference between two surfaces.Is it possible to do it in MATLAB?
   For example we have a sponge. I want to find difference between former sponge and after I put it in the water.There are two surfaces.
   Tnx

   @Roya,

   What would it mean to find the difference between two surfaces? Please give a 3×3 example of the before and after sponge along with what the answer would be.

   Doug
