Porting code to c++
显示 更早的评论
Dear all,
I am running a MATLAB code employing a function optimisation using the pattern search algorithm (the poll method used is GSS positive basis 2N and I am using the parallel computing option). For a variety of reasons (including IP) we want to port the code into C++. Can you please suggest a numerical library, possibly MIT licence or similar, that allows me to perform the same task (pattern search with parallel computing) with decent performance?
Thanks!

Could you use the Compiler SDK to build a C++ library directly? This would reuse your exact implementation with patternsearch and parallel computing.

Wouldn't that be subject to the same license restrictions as the copy of Matlab that created that library? Or am I misunderstanding how this works?

You're misunderstanding how it works. The whole purpose of the Compiler SDK is to build scalable applications that are encrypted and totally royalty-free.

The Compiler SDK lets you build C++ shared libraries rather than executables like the regular Compiler.

MATLAB Compiler doesn't transpile to C++; it doesn't write C++. It packages the MATLAB code up with a C++ interface, to run against a runtime. So it's the exact same code running against the same MATLAB execution engine and supports almost all of the MATLAB language and Toolboxes.
MATLAB Coder transpiles MATLAB code to C, C++. I.e. it rewrites it. This has more limited support and is generally targeted for embedded applications.
Your goal of having royalty free, IP protected, MATLAB code matches better with the Compiler SDK workflow.

It's running the same code against the same engine. The only change in performance will be if the compiled library is used on a more powerful machine.

Hello!
You can try the famous OpenCV library. It also has inbuilt constructs to parallelize your code. It uses the BSD 3-Clause licence.
You could also check out MATLAB Coder. It allows you to convert your MATLAB code to C/C++ code. However, not all MATLAB functionalities are supported for conversion. You can refer the following link to check for the same:
Thanks

By numerical optimization, you mean this? https://docs.opencv.org/3.4/da/d01/group__core__optim.html

Oh, I see. In my knowledge OpenCV doesn't support it. You need a "non-linear direct search optimization library". I did some googling and found one with LGPL licence: https://software.sandia.gov/opt++/opt++2.4_doc/html/index.html
This could be useful for your case.
