I’m afraid I do not know enough about vector fields to help. I suggest you post a question on MATLAB Answers or ask technical support. Good luck.

Thanks for nice videos. In my case I have an array of measures from 3D space. My array is A=(7,7,7), each element is least negative value of the measured signal like (-0.77). In principle it is a vector, because I am measuring ultrasound signals in the water and as I get closer to the focal point the signal intensity increases but I don’t need to show the direction, I am just interested in the intensity of the signal in 3D space. I could not figure out how to use quiver3 or scatter3, or cane plot for visualizing my data. I would appreciate if you could help on this.

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

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

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.

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