How can I enable directional derivatives in JModelica FMUs?
I couldn't find any information about that compiler flag.
Thanks
Directional derivatives are not available from JModelica.org generated FMUs and it is not planned to add it. It will though be added to the commercial tool OPTIMICA Compiler Toolkit which is based on JModelica.org

I am supposed to work with an existing code in my work and at some places the previous programmer has extensively used Fimath function. Unfortunately, I am not having the license for the Fixed Point Designer toolbox and was looking for some alternatives.
I tried getting the fimath.m file from another source but it is referencing to some embedded libraries in the toolbox.
Is there some other way in which I can bypass this problem?
Thank You
I need to localize facial landmarks as a part of my research project and planning to use Supervised Descent Method (SDM) for that. Both the C++ and Matlab versions are available at the following site and when I contacted them they said C++ version is not going to be available until they secure it. So, I had no other option and had to opt for Matlab version.
http://www.humansensing.cs.cmu.edu/intraface/download_functions_matlab.html
The problem is that My project is in C++ and OpenCV. I wonder whether there is a way to access Matlab version of SDM in Visual C++ . I mean, is there an integration mechanism available for that ?
And, the next issue is when executing the "Facial Feature Detection" code available at the above site I get the following error.
I executed it as given below.
[detected_points] = xx_track_detect(Model,[],image,[],options);
and, it says "undefined function or variable named 'model' "
anyone have a solution to this ?
It seems like you need to use Matlab engine to be able to execute Matlab commands from C++. The engine interface allows you to do just so.
Regarding the model variable - it is probably a representation of the learned model for facial landmarks, it should be supplied with the packge or you need to tune it by yourself. Without additional information I suggest you contact the publishers of the package for more information.
I'm working on a cosimulation in simulink using either 2012a or 2011b, and System Generator 13.1. When building the library block for the hardware to be loaded onto the zynq fpga, I configure the system generator to be a 'Hardware Co-Sim,' everything through this step works. However, in the simulink/pc end of the simulation, I haven't found any good resources for how to configure. Am I correct in assuming it also should be set as a hardware co-sim and not some other setup (HDL netlist) or anything like that?
Currently, the system seems to be loading the block just fine, but the jtag library is missing, not sure if this is a sysgen issue, or software versioning issue. My understanding is that sysgen is still in beta for 2012a.
Thanks in advance.
Yes, it should be set as a hardware co-simulation (Your board->connection type).
Configuring of board occurs when You start simulation. (Or You can program it manually using Impact and next check "skip configuration" in block properties).
I am working on an academic research regarding some very long functions in the Linux kernel (link, link).
For that research, I would like to use some code flow visualization tool, that would be able to plot a graph in which each vertex is a decision point and each edge is a piece of code which runs in a consequent way.
Do you know of any good, open source project that can visualize C code?
Perhaps a tool like KCacheGrind would be of help. It generates call graphs based on actual calls and cannot pre-generate a call graph without actually running the program, which may not suit your needs, but then it again it may.
History flow's are very neat for changes/diff across multiple versions.
Codeplex has a project, Dependency Visualizer which does support C also.
Gprof2Dot can render oprofile, this would get you dynamic info also.
CodeViz also (static tool) would work.
If your using gcc, gcc-xml has an introspector plugin also todo this.
You appears to want to acquire a flowchart of C source code ("decisions", "code blocks").
Something like this C flowchart?
To do this correctly, esp. for Linux kernal code, I'd expect you to have to preprocess the code first to get rid of macros and conditionals. I would assume that GCC would construct such a graph internally and that you ought to be able to get your hands on that graph.
Doxygen does some amount of 'visualization',
but you need to work on the code a bit for it to be usable.
Another interesting thing to check would be lxr
Linux Cross Referencer is a software toolset for indexing and presenting source code repositories. LXR was initially targeted at the Linux source code, but has proved usable for a wide range of software projects. lxr.linux.no is currently running an experimental fork of the LXR software.
I can recommend Sourcetrail. Can work with a compile_commands.json. Not sure if it's still maintained, though. But it's foss and you can fork it!
Does anyone know of a (purely) matlab implementation of Haar feature extraction (the kind used in Viola&Jones object detection algorithm)?
(I ran across a matlab binding to Opencv's implementation but this is not what I am looking for)
I came across this code published as part of a Google Summer of Code 2007 project under GNU GPLv2 license.
Face detection for F-spot
Note that I haven't tested it myself, just thought it could be useful for you..
