You should have a look at the HART toolbox (Hardware Access in Real-Time): http://hart.sourceforge.net/ As far as I know it works also with Scilab 5.41. We use it all the time to control hardware with "soft realtime" (Scicos/Xcos running) or "hard realtime" ( RTAI executable generated from the Scicos/Xcos diagram).

Pin?on work), I was wondering if his modified in-place insertion algorithm had been also implemented ? On the same topic I have a question/request : I some applications a sparse matrix needs to be updated at each iteration of an optimization algorithm, e.g. when the elements of this matrix depend on parameters which have to be identified. In such a case, the sparsity pattern does not change, but all the elements of the matrix need to be updated as fast as possible : this is impossible to do this in an efficient way in scilab, since in place insertion of new elements needs to write an explicit scilab loop. For example, once a sparse matrix has been built like this : M1_ijv=[1,137,v(3) 1,13,v(10) 1,19,v(12) 1,1,-(v(7)+v(9)+v(11)+v(66)) 2,138,v(3) 2,14,v(10) 2,20,v(12) [...] 151,151,-(v(43)+v(43)+v(60)+v(73))]; M1=sparse(M1_ijv(:,1:2),M1_ijv(:,3),[n1,n1]); Once v has been modified it should be possible to do something like : entries=[v(3) v(10) v(12) -(v(7)+v(9)+v(11)+v(66)) v(3) v(10) v(12) [...] -(v(43)+v(43)+v(60)+v(73))]; spset(M1,entries); If I am right, the internal storage of scilab sparse matrices uses a contiguous vector of the above nonzeros entries and two vectors of indices, It should be easy to implement such a "spset" function. Do you think it is worth writing a SEP ? S. -------------- next part -------------- An HTML attachment was scrubbed...

Scilab is not threadsafe. That means that call with Javasci or Call_scilab should be serialized (one after the other). If you want to go with parallel computing with Scilab, you should have a look to the MPI branch but it is a quite different paradigm.

Right now I am working on a specialised alternative for ?getvalue(..)? (GUI to edit parameters of Xcos blocks) written in Java to support my own blocks. I need to access the current Scilab workspace (execute an expression and get back the result) from Java -- something like { x = myScilab.getResultFromExpression("2.0*sin(foo)") } with an error message in case of a non-valid expression. Mostly it will be used to access variables defined by an initialisation script. Current means that the java code of interest is run through JIMS and shall access its calling Scilab environment. Where can I find this functionality? What I tried: Javasci: Used in a separated session it provides roughly the ask functionality. See the example included in Javasci. Used within an existing Scilab session I run in some problems. The sci.open() does not return when called from within a Scilab session and is probably not needed as there are static methods like Scilab.getInCurrentScilabSession(..), too. sci.get(..) is working when I skip sci.open(). Maybe that is the cause for the further problem with sci.execException. Scilab.getInCurrentScilabSession(?foo?) is working (returning a Scilab variables content) but I found one strange behaviour: Scilab.getInCurrentScilabSession(?foo * 2?) returns the value of foo, not 2*foo and not an Exception. This happens also when called as separate session. When called from within a running Scialb session sci.execException(?X2C_JAVA_ACCESS = 987?) (or any other valid expression) throws org.scilab.modules.javasci.JavasciException$ScilabErrorException: A Scilab error occurred: winqueryreg: Cannot query value of this type. Code: 999 and called one more time: org.scilab.modules.javasci.JavasciException$ScilabErrorException: A Scilab error occurred: Method invocation: An error occurred during the data retrieving in Java:An exception has been thrown in calling the method getValueFromExpression_1:org.scilab.modules.javasci.JavasciException$ScilabErrorException: A Scilab error occurred: winqueryreg: Cannot query value of this type.Code: 999 Code: 999 In a separate session as in the Javasci example that works.
