How many of you are using Octave or Scilab open source products
for simulation?

How well do they work?

Thanks,

I did use Scilab a bit. I tried using Scilab to solve a significant
motion profile generator problem. I found that Scilab's debugging
didn't work very well. HMI programming is awkward. I went back to
C and C++. I haven't used the Scicos part which is what you really
should be asking about since it directly competes with SimApp.

OTOH, I use Scilab all the time.

I stopped using Simulink the second time I had a big simulation break
thanks to a MatLab upgrade, so I'm out of the habit now with Scilab.

The debugging has gotten miles better in recent versions, although
the move to 5.0.x was huge (they migrated from Tcl to Java) and
they're still shaking the bugs out.

I didn't notice the migration to Java. I will look into it. That may
restart my interest.
Right now I am writing a hydraulic servo simulator in java. I had
considered doing it in Scilab but switched to Java when my previous
project didn't work too well.

Is simapp or Scilab widely used in control engineering? As far as I
know, in China, we mostly use Matlab and Simuboth in both industry and
academics. Scilab is used in some embedded systems to run some
complicated algorithms.

I can get Matlab with all the toolboxes and extra bits I need to do
control engineering with about the same amount of money as I could spend
to get a nice, reliable, late model used small car. Then the next year I
can get it all upgraded for the price of a major repair to the car.

I can get Scilab for the price of a download, it does nearly everything
that Matlab does plus plenty that Matlab doesn't, and upgrades cost
nothing.

Since I don't have a big corporation with more dollars than sense backing
me, guess which one I use.

How much does a Matlab seat with all the control systems trimmings cost
in China?
