I have a Matrix which I have turned into a 3D image using mesh. How can I calculate the volume of this matrix? I am trying to find total displacement across the Matrix.

You could go row by row and trapz(), sum all of those, multiply by the row width to get the volume.

Hi Walter,
I've got a similar question to Nels, I guess. I'm new to MATLAB.
I have plotted a bathymetry from xyz data file. Now, I have to calculate its volume. How should I do it?
Hope to hear from you soon!
Thanks,

Start your own question (a new, separate question/discussion) and attach your data file and m-code to read it into your volumetric array.
