Simulation With GNU Octave

With Matlab, It should be easy to make movie from
the figures by using getframe and movie functions.

In Gnu Octave (version 4.0.0), we do not have these two
functions to make movie. We have to use sprintf and print 
functions, and the following steps:

In the working directory, set a new folder , say output
to get the figures ( in .png format)

Call the widows the command line (prompt)
to execute the ffmpeg (other software of kind mencoder 
or ImageMagic to compact figures toa movie), that gives
a .avi or mp4 file.
