I have a 2D matrix (attached) containing the height information of a 3D object. I would like to know how to calculate the volume and total surface area of this mesh plot. considering each square pixel has a side length of 0.1 microns.

I’ve not done surface or volume integrals in a while, so I went back to Thomas and Finney.
See if this does what you want:
D = load('siddharth rawat h1.mat');
h1 = D.h1;
Vol = trapz(trapz(h1));
DxDy = gradient(h1);
Surface = trapz(trapz(sqrt(DxDy.^2 + DxDy'.^2 + 1)));
Vol =
6668.8
Surface =
11368

i want to find out the Mean corpuscular volume (MCV). for mcv we must have volume of red blood cells so my question is how to calculate the volume of red blood cells for which i have also attached the image of normal red blood cell. any answer will highly be appreciated.
