I need to run some mathematica commands inside matlab codes. Looking around I found there used to be two alternatives for this:
-SMATLink (http://www.mathworks.com/matlabcentral/fileexchange/20573-smatlink-let-matlab-dance-with-mathematica)
-Mathemtica Symbolic Toolbox for MatLab (http://www.mathworks.com/matlabcentral/fileexchange/6044-mathematica-symbolic-toolbox-for-matlab-version-2-0)
Both are old however and won't run on newer versions of MatLab. Does anybody know an alternative? MatLink only seems to interact Mathematica with MatLab by running commands in Mathematica, so it does suit not my needs...
Thanks in advance.

What is the simplest way to compile m-file without installed matlab?
And can someone say when will users get possibility for compiling programs with training networks (not only using training networks in compiling)?
MATLAB is not a compiled language, it is interpreted at runtime, so you need to have MATLAB installed to run a m-File (script). You can use the MATLAB compiler software to create a standalone application from an m-File or a function.
To run an m-file without having MATLAB, you can use GNU Octave. Octave is an open-source software which has almost the same syntax and functionality as MATLAB. They are not 100% identical though, so you will have to migrate your script. As mentioned in this question, code which runs in MATLAB will almost always run in Octave too, so it should work quite well.
for very basic scripting you can use this online octave(/matlab) compiler I found http://www.tutorialspoint.com/matlab/try_matlab.php There are some limitations of course, but for basic scripts it works well
I've been searching around for some way to easily interface opencl code with MATLAB code, however most of what I've found is several years old and I'm wondering if it's still applicable.
Does anyone know of a way to do this?
Have you tried the OpenCL Toolbox?
Also the MATLAB Parallel Computing Toolbox may be a useful alternative if you have the license for it.
Also see Jacket.
The last two may require you to rewrite your code in the matlab language, if that is an acceptable price.
I'm trying to compute the autocorrelation of my timeseries. This work on my laptop with matlab R2011a, but not on my desktop with matlab R2013a. I read somewhere that the Signal Processing Toolbox needs to be installed, and that is the case on both of my computers. There seems to be no function at all called autocorr, but I can find it again on the matworks documentation for 2014b. I have the same problem with xcorr, although matlab seems to recognize the function ('help xcorr' works, 'help autocorr' not).
How can I fix this?
I am trying to get the MATLAB toolbox SOSTOOLS to work inside a MATLAB R2010b (7.11.0.584) but get the following error:
??? Error using ==> maple at 54 The MAPLE command is not available.
Googling it I found out that MATLAB stopped using Maple at some stage and switched to MuPad.
Short of switching to an older version of MATLAB, is there a known workaround for this situation?
A solution in the form of installing Maple as the symbolic toolbox engine is not possible with your version of Matlab.
This outlines an alternative possible solution, I did not find a concrete workaround that will spare you work. I recommend you contact the authors, or check for octave versions with the same functionality.
The change to MuPad is a problem that's been posted numerous times, and there is a useful discussion of differences between Maple and MuPad here:
http://www.walkingrandomly.com/?p=178
For some commands it looks like a simple translator might work. Most of the implementation would apparently be in parsing the output from MuPad and turning it into what Maple would generate. The input to MuPad and Maple is apparently equal most of the time, but read the doc above.
To write a translator, you redirect calls to maple by placing in your path the following function maple that calls mupad:
function output=maple(input);
%prepare input here (if necessary) ...
output=mupad(input);
% parse the output (if necessary) ...
More likely than not, a naive call to this re-director will not solve the problem without some input/output parsing.
Is it possible to use a MATLAB code on Scilab? Is that what is meant when saying that Scilab is a "clone" from MATLAB?
There is a tool to automatically convert Matlab source to Scilab source, it's called M2SCI. A script parses the Matlab source code and replaces Matlab-specific functions by Scilab ones. See the documentation of the mfile2sci function.
Yes you can use MATLAB code on scilab. See these links for more information:
http://help.scilab.org/docs/5.4.0/fr_FR/section_36184e52ee88ad558380be4e92d3de21.html

I would not bet on it. But if your code is simple enough chances are good.
Problems are:
There is encrypted p-code in Matlab that Scilab will not be able to open.
Matlab usually comes with a number of toolboxes that might not be available to you (i think especially Simulink)
last but not least (i don't know about scilab) there usually are minute differences in how functions are implemented.
There are a number of projects out there trying to replicate/replace MATLAB:
Julia language: which has a relatively similar syntax to MATLAB and offers great performance, but still lacks a lot of toolboxes/libraries, as well as not having a GUI like MATLAB. I think this has the brightest future among all MATLAB alternatives.
Python language and its libraries NumPy and matplotlib: which is the most used alternative. I think at this moment the community is a couple of orders of magnitude even bigger than MATLAB. Python is the de facto standard in machine learning and data science at the moment. But still, the syntax and memory concept is a bit far from what people are used to in the MATLAB ecosystem. There are also no equivalent to SIMULINK, although Spyder and Jupyter projects have come a long way in terms of the development environment.
Octave: is basically a clone of MATLAB to a point they consider any incompatibility as a bug. If you have a long MATLAB code that you don't want to touch, this is the safest bet. But again no alternative for SIMULINK.
SciLab and it's fork ScicoLab are the best alternatives in terms of GUI, having a SIMULINK replica xcos / scicos and a graphical user interface development features. However the community is not as big as Octave and the syntax is not completely compatible. Sadly the Scilab development team has gone through a devastating family crisis leading to the software falling behind.
Honorary mention of Modelica language implementations OpenModelica and jModelica for being a superior alternative to SIMULINK-SimScape. You should know that you can load Modelica scrips also in xcos and scicos. If you want to kno wmore about JModelica you may see this post.
