MathWorks today announced Release 2013b (R2013b) of its MATLAB and Simulink product families. R2013b delivers new analysis, design, code generation and implementation and other features in MATLAB and Simulink, two new Polyspace products, as well as updates to 79 other products. Highlights include:
MathWorks is the leading developer of mathematical computing software. MATLAB, the language of technical computing, is a programming environment for algorithm development, data analysis, visualization, and numeric computation. Simulink is a graphical environment for simulation and Model-Based Design for multidomain dynamic and embedded systems. Engineers and scientists worldwide rely on these product families to accelerate the pace of discovery, innovation, and development in automotive, aerospace, electronics, financial services, biotech-pharmaceutical, and other industries. MathWorks products are also fundamental teaching and research tools in the world's universities and learning institutions. Founded in 1984, MathWorks employs more than 2800 people in 15 countries, with headquarters in Natick, Massachusetts, USA. For additional information, visit mathworks.com.

Since a couple of days, I constantly receive the same error while using MATLAB which happens at some point with dlopen. I am pretty new to MATLAB, and that is why I don't know what to do. Google doesn't seem to be helping me either. When I try to make an eigenvector, I get this:
MATLAB dynamically (with dlopen) loads several libraries that need tls initialization. All those libs need a slot in the dtv (dynamic thread vector). Because MATLAB loads several of these libs dynamically at runtime at compile/link time the linker (at mathworks) had no chance to count the slots needed (that's the important part). Now it's the task of the dynamic lib loader to handle such a case at runtime. But this is not easy. To cite dl-open.c:
For static TLS we have to allocate the memory here and now. This includes allocating memory in the DTV. But we cannot change any DTV other than our own. So, if we cannot guarantee that there is room in the DTV we don't even try it and fail the load.
There is a compile time constant (called DTV_SURPLUS, see glibc-source/sysdeps/generic/ldsodefs.h) in the glibc's dynamic lib loader for reserving a number of additional slots for such a mess (dynamically loading libs with static TLS in a multithreading program). In the glibc-Version of Fedora 20 this value is 14.
For the record: In order not to violate MATLAB's license I didn't debug, decompile or disassemble any part of the binaries shipped with MATLAB. I only debugged the free and open glibc-binaries of Fedora 20 that MATLAB were using to dynamically load the libs.
I really tried to explain this to the "MathWorks Technical Support Department". But my impression is: they don't understand me. They closed my support ticket and suggested a telephone(!) conversation in January 2014 with a technical support manager.
Update (2014/03/19): For the file libiomp5.so you can download a newly compiled version (without static TLS) at mathworks, bug report 961964. And the other libs? No improvement there. So don't be suprised to get "dlopen: cannot load any more object with static TLS" with "doc", e.g. see bug report 1003952.
The solution is to inform MATLAB to load the specific library at the earliest of its startup. The reason for this error is apparently due to the lack of slots for this thread local storage aka tls purpose (due to they already been filled-up).
has been updated on 30/01/2014.There is a zip file attached with libiomp5.soI tested it on Mageia 4 x86_64 with Matlab R2013b.I can now use the Documentation of Matlab to open a demo without any problem.
When installing matlab use the custom installation (I did not do this the first time). Choose to create symbolic links to matlab scripts in the predefined folder (/usr/local/bin). This did the trick for me!
I had the same problem with both Matlab 2013b and Matlab 2014a. The fix provided by mathworks for libiomp5.so only removed the problem of LAPACK not working. However, I could not use external libraries which are using OpenMp (such as VL_FEAT): I still get the error "dlopen: cannot load any more object with static TLS."
I came across this problem after "bar" (for bar plots) with a an array gives me just a single blue block, with no errors thrown. Reboot at first solved the problem. But after a memory error (after processing a very large file), I just cannot get past this blue block problem.
Increasing Java heap memory (to 512 mb) also worked for me on R2013b/Ubuntu 12.04. The "BLAS loading error" began when I processed an 11 GB file (with 16 GB RAM), and has not recurred after increasing java heap memory and restarting matlab.
Hi,
I have created a script, that will run current m-file opened in Sublime in Matlab after pressing any custom set key short cut. It will use opened instance of Matlab or will open a new one if none is open. Please find more information on github.com/jirkadus/sublime2matlab. I will be happy for any feedback, as at the moment is is strongly customised for my needs.
Footnotes 1AutomationDesk MATLAB Access Library supports the remote access to 64-bit MATLAB releases starting with dSPACE Release 2014-A. However the same MATLAB release must also be installed as 32-bit version. If the MATLAB Access Library is not required, AutomationDesk can also be installed and used without MATLAB 64-bit support.2HIL API.NET cannot be used in 64-bit MATLAB releases. Because there are no further dependencies to MATLAB, it is possible to use it outside of MATLAB.3matlablib2 supports the remote access to 64-bit MATLAB releases. However the same MATLAB release must also be installed as 32-bit version.4 MLIB/MTRACE last time available in dSPACE Release 2013-B.5RTI AUTOSAR Package last time available in dSPACE Release 2014-A.6It is necessary to install Service Pack 2 and RTI Bypass 3.2 Patch 2. Patch Setup does not ask for license files. But you will need the proper RTI Bypass license before you can use the blockset. If in any doubt, use Installation Manager to check for the license and add it if missing.7Introduced with Release 2013-B Implementation-Software Service Pack 3.
