Hello,
I want to create a 4*4, 2 dimentional mesh of an image of a composite material (containing an inclusion).
I have tried to collect data from the image using the function size, however i do not know how to procede for the mesh.
Thank you.

Your question is still not clear to me, and I can't run your code because you decided to post it as an image.

rows=251;
columns=257;
[R, C] = meshgrid(1:10:rows, 1:10:columns);
r=size(R)
c=size(C)
Z=zeros(r(1),c(2));
T = delaunay(R,C);
trimesh(T,R,C,Z)
view(0,300)
I have been able to visualize a mesh of a rectangle, as shown in this figure:
I want now to mesh a circle inside of it(wich will represent the inclusion).
Your help will be appreciated.
