I have 10 figures, I wanna control their visibility. I did the following to set visibility for each figure. These figures belongs to 5 different functions. Hence, whenever I wanna change the display of figure (for example, I wanna display 1,5,9 now, later I wanna display something else, say 2,5,8), I need to edit/change the function itself.

h1 = figure(1); imshow(edge)
set(h1, 'Visible','Off')

any suggestion how to control the visibility without editing those function, i.e. writing a script or something like that to control which figure number to display?

You didn't say how it was to be decided which figures would be displayed or hidden. For example, you could have a GUI with 10 checkboxes on it, where the user can check which figures he wants displayed. The callback of the checkbox would run your code to show or hide the figures.

在 MATLAB Online 中打开

function showfigure(fignum)
  set(fignum,'Visible', 'off');
end
function hidefigure(fignum)
  set(fignum,'Visible', 'off');
end

Now you can showfigure(5); hidefigure(7);

You can even set things up like this

function showfigures(fignums)
  tohide = setdiff(1:10, fignums);  %1:10 reflects the 1 through 10 you used
  set(fignums, 'visible', 'on');
  set(tohide, 'visible', 'off');
end
