I have a matrix of number which represent the material distribution in finite elements. How can I create a finer mesh with these matrix in MATLAB? I need a code which I can use to create a remesh/finer mesh. For example, let us say I have a 30*30 matrix which denote the material distribution in finite elements. I need a code that I can use to generate a remesh/finer mesh in MATLAB. Thank you.

Can you show what you want with an example? image..a hand drawn image at least.

You can use imresize(). Something like this should work.
% Initializing a sample image
myImage = [0 1 1 1; ...
1 0 1 1; ...
1 0 0 1; ...
1 1 1 1];
imshow(myImage,'InitialMagnification',10000)
% using imresize to resize the image and refine it.
myRefinedImage = imresize(myImage,2,'nearest');
imshow(myRefinedImage,'InitialMagnification',10000)
Check the method options. if the value in image are label to a certain material so you need to use nearest. However, depending on your application you might need to use other methods.
