variance calculating function
Hi there, I had implemented a variance actor , which calculates simple variance given an array...however I was wondering if i can do the same with _expression_ actor? I couldn't find a variance fcn is there one? thanks, nandita. Be a chatter box. Enjoy free PC-to-PC calls with Yahoo! Messenger with Voice.
Ptolemy Documentation Infrastructure question
Hi Edward, I wanted to ask you a code specific question in "GetDocumentationAction" from the following scenario when if a docAttribute exists (i.e CustomizeDoc has been called and docAttribute was added via MOMLChangeRequest). In this case , (correct me if i am wrong) we get the DocAttribute and display it via the DocTableau. However I am unsure where the javadocs information is called in this process i.e ports n params information and how that is displayed as well in the DocTableau. I believe in Ptolemy when one customizes documentation both newly added docAttribute as well as original ports/params information show up. However I am unsure how & where ports/params info (from doc/codeDoc/classname.xml in case of Ptolemy) is made to show here in the DocViewer. I am trying to solve a Kepler bug where CustomizeDocumentation deletes all previous ports/params information for some reason and only shows the newly added
"DocAttribute" information. Another interesting point in this case, is that if i just click on "CustomizeDoc" and click "cancel"...even then an empty docAttribute is created in the MOML as follows: The above also shows no actor documentaiton in DocViewer. "GetDocumentationAction" from the Ptolemy documentation structure is the only class that i have customized in Kepler. (where i only change location of javadocs from doc/codeDoc to a Kepler-Docs location) Kindly feel free to correct my understanding of Ptolemy's documentation structure working if I am wrong. Thanks so much. nandita. //From "GetDocumentationAction.java" DocAttribute docAttribute = (DocAttribute) docAttributes

ptolemy matlab
hi there,I am currently using gcc version 3.4.4 with cygwin. Is that version known to be compatible with the Ptolemy Matlab interface?Currently running make under ptolemy/matlab gives gcc: no input files error.( i am in middle of downloading cygwindevel.exe but unsure if gcc version with that cygwin installation is 3.2 or not)I have matlab 6.5 installed (WIndows os)thanks!nandita.

Storing XYPlotter graph as video
Hi there, I had a question, if there are any actors /ways to store the results plotted on an XY Plotter as a video? My workflow continously plots data in a loop and can i store the result at some point as video? If not can i store graph as an image? thanks! nandita. Do you Yahoo!?

Re: Importing jar files
Hi Chirstopher, Thanks for looking into possible reasons for the exceptions. I don't get any exceptions when the vergil shows up the JAI actors now , as you suggested JAI implementation jars namely jai_core.jar & jai_codec.jar needed to be placed it in the right JDK. Currently I have the class files for all JAI actors in ptolemy/actor/lib/jai & the implementation jars in the JDK folder.However, now when I run the the actors/ other demos , I get the following exception: Error: IOException occurs when search for propriate codecs.

Importing jar files
Hi there,I have a very basic question on importing the jar files for the JAI actors.Currently I am able to make the class files in pttII/ptolemy/actor/lib/jai folder.And when I run vergil (it shows up JAI actors with exceptions)basically I am unable to make ptolemy load the jai jar files during vergil. I placed the jar files in actor/lib. I refered to "Add an Actor" page & my actors do show up , but am facing the jar issue, probably not doing something right... thanks, nandita. __Do You Yahoo!?Tired of spam? Yahoo!
