RE: Control toolbox having ss2tf, tf2ss, ss2sys, tf2sys, lsim, etc missing

[Shrikrishna.Joshi]

my query:

The command of "axis" is ignored if we plot in the for loop.

 With earlier version on IRIX operating system the command was honoured.

 

 

your comment:

You haven't really supplied enough information. As far as I can see the

axis command works as expected.

 

 

I am simulating crank-piston mechanism with torques and forces applied.

I wanted to visualize / animate the mechanism after solving it.

For this reason I gave the following command:

 

axis([-1 5 -1 5],"square");

for k=1:10:length(Xa)

system(" ",sleep(0.05));

plot([xo Xa(k) Xb(k)],[yo Ya(k) Yb(k)]);

end

 

another variant

 

for k=1:10:length(Xa)

system(" ",sleep(0.05));

axis([-1 5 -1 5],"square");

plot([xo Xa(k) Xb(k)],[yo Ya(k) Yb(k)]);

end

 

The plots however are plotted with auto limits and the axis command is ignored.

Due to which the plots look quite distorted.

Kindly suggest workaround.

The control toolbox was removed from Octave itself and became an

octave-forge package. Check

 

http://octave.sourceforge.net/control/index.html

 

You might also what to look at the control-oo toolbox that is more

matlab compatible. Though as this toolbox is in development you'll need

to get it from the SVN. See

 

http://octave.svn.sourceforge.net/viewvc/octave/trunk/octave-forge/main/control/
