I am new here. I tried to write a function in VS code, but when I start to write the parameters name in the function block, they don't pop up. Also like you can see in the print screnn, they also shown in white.
Someone know what is the reason?
btw, also I have some error, but I don't know what the VS code wants.
Thanks
I am trying to run Kevin Murphy's Bayes Net Toolbox in Octave and encountering some problems. It doesn't help that I'm a novice at Bayesian networks, Matlab and Octave.
This toolbox was originally written for Matlab. There is a large test file called test_BNT.m which runs through all the functionality in the toolbox. Most of the error messages relate to the difference between & and && in Matlab and Octave. This is easy to fix. However, I've now come across a new problem and I don't know what to do about it.
For instance, the qmr1.m script creates an instance of the pearl_inf_engine class, sets some of the member member variables and passes the instance of the class to another function. Later on, the member variables are accessed again in a different script (parallel_protocol.m). But when this happens, the following message appears:
error: invalid index for class
error: evaluating argument list element number 1
It seems that from one script to another, it has forgotten that the class has any member variables and gives the invalid index message when you try to access them.
Is this a common error with an easy solution? Is something wrong with the path or working directory? Maybe someone else has already converted the BNT to octave and knows what to do?
Edit
I was able to get past this error message. The trick was to read the installation instructions (haha) and run addpath(genpathKPM(<BNT base directory)). genpathKPM.m is a script includes in BNT which adds all the required directories to the path.
After doing this, run test_BNT.m and change & to && and | to || at each line where it gives a warning. This will clear up most of the errors.
However, I'm still unable to run mpe1.m, mp2.m, mildew1.m and some others. The new error message I'm stuck on is:
error: invalid empty index list
error: called from:
error: C:\FullBNT-1.0.7\bnt\BNT\inference\static\#var_elim_inf_engine\find_mpe
.m at line 63, column 5
on this line of code:
eval(['sCPT.T(', sargs, num2str(jj), ')=0;']);
If I can get all the scripts to work, I'll post an answer here with the steps I took to do it.
Edit 2
I was able to get past the problem in the previous edit. Replace
eval(['sCPT.T(', sargs, num2str(jj), ')=0;']);
with
eval(['sCPT.T(', sargs, sprintf('%d',jj), ')=0;']);
The next problem is identical. Just replace num2str in the same way.
This file was apparently contributed by a user of BNT, and not written by the original author. Using eval kind of a hack, I think. A better fix would be to just rewrite the code so it doesn't use eval at all.
There is one more error in draw_graph.m, which was apparently also an outside contribution to the project. I just commented out the call to that function since I'm not interested in drawing graphs right now. After doing this, and continuing to fix shortcircuit operators, all of the tests in test_BNT.m will run.
Still, I won't create an answer for this until I can get draw_graph.m to run, too.
As a significant amount of time has passed, and the answer to the core problem was provided in the question, I will post it here so it will not stay listed as unanswered:
tl;dr: Change a few operators, solve the remaining bugs specified below, and everything works except the drawing of graphs.

I have an issue with my ModX Evo site throwing this error:
Fatal error: Cannot redeclare insert_metka() (previously declared in /home/mysite/public_html/manager/includes/document.parser.class.inc.php(794) : eval()'d code:2) in /home/mysite/public_html/manager/includes/document.parser.class.inc.php(794) : eval()'d code on line 12'
I have searched and searched but cannot find where insert_metka() is declared. I even downloaded the entire site and ran a search to no avail. I also tried to updated the version to the latest, also to no avail.
Can anyone please tell me where to find this function?
Download a database dump and look for the this line in it. It seems that the fault one of the plugins, try disabling plugins until you find it. See ModX Evo: PHP error in document.parser.class.inc.php for more advices.
As you can see from your error-code, the function was declared in a snippet. This is because Modx has this way of caching snippets to speed up the performance. They make static files of your snippets wrapped as a function.
This may cause errors if the same function is called twice and you declared a function within it. I suspect that is what is going on here.
To solve this issue, simply wrap your entire function in function_exists like so:
if (!function_exists("insert_metka")) {
function insert_metka() {
// Stuff goes here
}
}
Sidenote: This is in addition to the answer given by Vasis. You should search your snippets, extras and plugins. It should be located somewhere in those files. It is not a function provided from the Modx core.
I have no errors show up in either the compilation or the hosted mode process, but the JS that GWT creates contain errors that disallow the proper rendering of the website. How can this happen? Is this a problem with the compiler?
FireBug is giving me nothing, no errors at all.
But I don't know where to go from here or what more information to give you all, since I can't effectively debug JS like this. More fundamentally, I just don't understand why GWT is giving me JS that doesn't work.
EDIT: I didn't really know what Pretty and Detailed meant until now. Thanks for pointing me to this. What I get now is http://i.imgur.com/qUyNb.png.
I'm not sure where to go from here.
EDIT 2: Here is the final image I will post (I promise!): http://i.imgur.com/ZVQVW.png. This is the pretty output. The error reads: "Uncaught com.google.gwt.core.client.JavaScriptException (TypeError): Cannot call method 'isString' of null (anonymous function)."
The resolution to this issue was the realization that isString was not a JNSI method, but instead a method I wrote in a try / catch block. This was the code that tripped me up:
try{something that will create a NullPointerException}
catch(NullPointerException npe){npe.printStackTrace()}
#Luismahou's link above said the following about error-catching in GWT:
Exceptions: try, catch, finally and user-defined exceptions are supported as normal, although Throwable.getStackTrace() is not meaningfully supported in production mode.
Note: Several fundamental exceptions implicitly produced by the Java VM, most notably NullPointerException, StackOverflowError, and OutOfMemoryError, do not occur in production mode as such. Instead, a JavaScriptException is produced for any implicitly generated exceptions. This is because the nature of the underlying JavaScript exception cannot be reliably mapped onto the appropriate Java exception type.
I think what happened is that my try block threw a NullPointerException, which was represented as a JavaScriptException and was uncaught by the catch block. Lesson learned: don't catch NullPointerExceptions, StackOverflowErrors, and OutOfMemoryErrors in GWT.
I'm trying to use smarttabs.el from https://gist.github.com/188961 in latest emacs-dev (bzr). When trying to compile or load it I get the error:
smarttabs.el:54:1:Error: Don't know how to make a localized variable an alias
which is completely new to me. How do I correct this?
Also see http://www.emacswiki.org/emacs/SmartTabs for package explanation.
The error message is trying to say that defvaralias (used in the smart-tabs-advice macro) doesn't do what jacius thinks it does. But I'm not quite sure what he thinks it does, so I'm not sure how to fix it. Try reporting the error to him.
