I have a binary 3D matrix (100*100*100), which is a digital rock. In the matrix 0 and 1 represent the pores and solid area, respectively. I want to represent some slices. For example in XY plane slices 1 and 50 and 100. How can I show just some slices of the rock?

Use slice()

Hello,

Could you tell me in case I have a matrix A=randi([0,1],[256,256,5]) and I want to show the plane B=A(255,:,:) but like a top view.

imshow(B) does not work because the image of B considered Multi-plane, B is 256*1*5 double

Have you tried to index them and use imshow? (so imshow(A(:,:,50)))

You can use subplot to show the separate images side by side, or you can use montage to show the entire matrix (don't forget to use permute to change your matrix from row x col x page to row x col x color x page).
