MATLAB: How to pass a binary input as an argument to the MESH command in MATLAB

Question

I receive an error when I pass a binary input to the MESH command. For example

executing

A = rand(3,3);
B = A > 0.5;
% B is binary matrix;
mesh(B);

throws the following error.

 ??? Error using ==> graph3d.surfaceplot.surfaceplot>localConstructor at 92
 Invalid input arguments
 Error in ==> mesh at 103
        hh = graph3d.surfaceplot(x,'FaceColor',fc,'EdgeColor','flat', ...

Answer 1

The MESH command does not take binary inputs directly. However, as a workaround you can typecast the binary inputs into a double before passing it to the MESH command.

A = rand(3,3);
B = A > 0.5;
% B is binary matrix;
mesh(double(B));
