MATLAB: Closing a specified figure (if exist)

closingfigurespecified

does anyone know how to close a specified figure if it exists currently? for example: h=figure

if h exists close(h) end

h = figure;
if ishandle(h)
close(h)
end

h =  findobj('type','figure');
n = length(h);

And you can set the properties of all three at once using their handles - stored in h.

h=figure
close(h)
