Managing a figure
At first a graphic figure should be prepared. It is possible to clear an existing figure or to generate a new one.
Launch the following commands :
num = 1234; scf(num) // create figure with number num or set figure num to the current figure clf(num) // clear figure num xdel(num) // closes graphic windows num
All plotting action will be done in the current figure. The variable num can be left out, to address the current figure (e.g. clf()).
