# Doug's MATLAB Video Tutorials

## Basics: Volume visualization: 1/9 Defining scalar and vector fields

This short video is the first of a series of nine that talks about volume visualization. Patrick gave this talk internally to help technical support engineers understand capabilities of MATLAB for volume visualization.

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!

Doug, you are such a tease…can’t wait to see the rest of this series…great topic!

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!
Doug

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

7. dhull replied on :

@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.

very great video series. always have wondered, how these commands worked and what they REALLY showed.

Wrap code fragments inside <pre> tags, like this:

<pre class="code">
a = magic(3);
sum(a)
</pre>


If you have a "<" character in your code, either follow it with a space or replace it with "&lt;" (including the semicolon).
