I want to see this matrix with different numbers displaying different colour in 3D.(like we use imagesc for 2D). Can anybody tell me which command is there for 3D image

You could use scatter3:
S = size(A);
[X,Y,Z] = ndgrid(1:S(1),1:S(2),1:S(3));
scatter3(X(:),Y(:),Z(:),321,A(:),'filled')
Use colormap to change the colors.
