Sorry for the long time no come. Because my family has some circs. I just realize plot the pane. And I don't konw how to come true that game. I konw it should be progammed in GUI. But i should know the basic programme first. The following step that I want to konw is how to fill the N pane among the 10*10 pane to black? N is random. Thank you for your help first.

Hmmmm.... Looks like Google Translate didn't do such a good job on that one. Maybe if you reviewed some of Doug Hull's video tutorials ( http://blogs.mathworks.com/videos/) on GUI development you might learn how to do whatever it is that you want to do.

pane = zeros(10,10);
temp_idx_to_fill = randperm(numel(pane));
idx_to_fill = temp_idx_to_fill(1:N);
[row_to_fill, col_to_fill] = idx2sub(size(pane), idx_to_fill);
Now fill the locations at [row_to_fill(1), col_to_fill(1)], [row_to_fill(2), col_to_fill(2)] and so on.

In your programme I didn't understand the function of idx2sub and matlab can not recognise it.

Sorry I should have written ind2sub() instead of idx2sub()
