Can you give some details about what isn't working? This works for me:
z = cumsum(rand(64)); % makes a 64-my-64 matrix
mesh(z) % makes a mesh plot

You can try something like this to represent your array as mesh:
% Example 2D data array (64x64)
data = rand(64, 64); % Replace this with your actual data
% Create a grid of x and y coordinates
[x, y] = meshgrid(1:size(data, 2), 1:size(data, 1));
% Plot the mesh
figure;
mesh(x, y, data);
% Add labels and title for clarity
xlabel('X-axis');
ylabel('Y-axis');
zlabel('Z-axis');
title('Mesh Plot of 2D Data Array');
Hope it helps!

Ran in:
In the case where your x and y are 1 to the number of points, you do not need to construct the x and y explicitly.
data = rand(64, 64);
mesh(data);
% Add labels and title for clarity
xlabel('X-axis');
ylabel('Y-axis');
zlabel('Z-axis');
title('Mesh Plot of 2D Data Array');
