I am having troubles understanding what this instruction is doing:
add 0x402780(,%rdx,4),%ecx
I've tried running through it with different values to figure out what it is doing, but still no luck.

I'm trying to plot the S-Parameters in a file .s4p using the RFtoolbox but it seams that the function that I need rfplot doesn't work.
I searched which rfplot to see if the function exsits, and it is, but it's empty. I opened and inside I have this line:
narginchk(1,Inf)
error(message('MATLAB:UndefinedFunctionTextInputArgumentsType','rfplot',class(varargin{1})))
I tried also with other versions of Matlab (I have R2017a) where I work, but everyone have this kind of function.
Do you know why? Al the other functions of RFtoolbox work perfectly. How can I solve it if this problem is not related to my version?
The function exist, and the code exist too, but its hidden. Its a MATLAB proprietary code and they do not want you to know the real code behind it, so you can not see it.
I'm learning from breeze-zza-mongodb sample.
I get some problems when i try to use the saveChanges() function from breeze.
This is the error i get:
"TypeError: Cannot read property 'update' of null at... node_modules\breeze-mongodb\mongoSaveHandler.js : 229:20 at Array.forEach"
Any of you tried and got this error? I searched Google for a bit longer but i can't find this issue. And if i try to manager.getChanges() and put the changes in array, i get my entity with modified state.
The guys from breeze didn't covered this part and i'm completly blind in this. Thank you for your time guys.
I solved my problem. I included the modules in VS so i can debug and i noticed that breeze misnamed my collection name for some reason adding an s at the end.
Anyway.. for now i just removed that, and it works. I will dig deeper to see where and why is breeze adding an s at the end of my collection name because i want to treat the cause, not the effect. 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'm using this peculiar syntax for assigning an object to an instance variable during a list iteration:
execute: =>
while #canExecute()
for #currentStack in #stacks
#executeNext()
if #currentStack.isEmpty()
#stacks.remove #currentStack
break
The important line here is for #currentStack in #stacks. This assigns this.currentStack during iteration. I like this. It makes me happy.
I'm worried though that it's an issue. I don't see it specifically documented anywhere. This code is running in several different products and I haven't found an issue myself. Anyone have experience with this?
You are using a pure javascript for...in loop, it is perfectly fine you can continue being happy. Link for documentation:

I'm working on a very large CGI application that uses Crypt::RSA, which is properly installed. I get a "attempted to call a null reference as a function" type of error (I can't go back to get the exact error right now because we had to rollback for a release date) when I try to run any the embedded library. I trace the null reference to Crypt::RSA's constructor, which uses Class::Loader to enable Crypt::RSA::ES::OAEP.
I replaced the class loader with a "use" and a "new", and that part works fine, though the library still fails in many points. Obviously something is wrong with my environment. I'm just not certain as to what. Can anyone give me any leads?
Ok, after 12 hours of digging into it, I got this working.
Here's what was going on (but not why). Whenever I called eval() on a quoted use or require statement (as occurs in Class::Loader, but also in other locations in the Crypt:: framwork), it failed to see paths that were otherwise included as Perl classpaths. Since most quoted use/require objects simply assume the class will be there, very few useful errors were thrown out at me. I would dump #INC to file, outside an eval block, and everything would be there.
Ironically, I used the same setup in dev vs staging, and it worked in dev, but not in staging. I must also point out that FindBin (I shouldn't be using it in CGI, I know, but Crypt uses it) was flailing up and down about /dev/null in staging, but not in development.
Since I can't easily compare versions or global configs, that's where my quest ends.
How I resolved the issue for myself in Crypt::RSA was to disable all commands tied to FindBin, and hard-code require references for anything my code would ever access. I did a require in Crypt::RSA for Crypt::RSA::ES::OAEP and one in Crypt::Random::Generator for Crypt::Random::Provider::rand
Hope this helps anyone in the future who has the problem. Anyone who can suggest the why of it, please respond and I'll add it to complete the post.
