How could I integate Matlab library into android?

Hi,

I'd like to use Matlab library to do some applications on android. How could I integate Matlab library into android? Is there any other methods to achieve what I want except Matlab Coder which could covert to C code?

You can use Simulink to build and deploy models to Android; see http://www.mathworks.com/help/supportpkg/android/ug/install-support-for-samsung-galaxy-android-devices.html

Hi Walter,

My thought is that I could build and call API from Matlab library in android. So, first I need to integrate Matlab library into android so that I could use Matlab function in android. And the reference you provide seems that I deploy the package to android after building code at local computer.

[Walter Roberson]

You cannot use the MATLAB library in android. For the last several years, the MATLAB libraries have only been compatible with Intel x86 architecture and x64 architecture. Android use a number of different chips, based upon the ARM architecture series.

Some parts of the MATLAB libraries are written in MATLAB, but the lower-level parts are written (I gather) mostly in C++, C, and a bit of Fortran, and only Intel-architecture binaries for those parts are made available.

Hi Walter,

I found that someone provide .jar files with Matlab Compiler Runtime(MCR) as the link below: http://stackoverflow.com/questions/9662730/how-to-integrate-matlab-code-library-with-android

Could I integrate MCR into android?

[Walter Roberson]

The .jar contains a bit of Java that calls into the MCR which is effectively a Intel x32 or Intel x64 architecture DLL.

Hi Walter,

I installed MCR(Linux version) and ther are numbers of.so files under /bin. Do you mean that these .so files are only available for Intel x32 or Intel x64?

[Walter Roberson]

.so files are Linux Shared Object libraries. Those .so files are only available for Intel x86 (32 bit) and x64 (64 bit) instruction set (including AMD CPUs that implement those.) They are not available for ARM or other instruction architectures.

The files created by MATLAB Compiler and by MATLAB Compiler SDK are only usable on the same kinds of systems that MATLAB itself would be able to execute on -- MS Windows, Linux, or OS-X systems, with x86 or x64 instruction sets.

Hi Walter,

Ok, I see. Is there any Matlab library for ARM architecture?

[Walter Roberson]

No, there is no MATLAB library for ARM architecture. There is just C/C++ code generation, compiling, scp, and ssh.

Potentially Simulink might be smart enough about the Android target that it might be able to take advantage of some standard Android math library, but I do not know if it can do that. I did some research last year and found a BLAS for Android; it was said to take about 2 1/2 days to compile from source as it did extensive testing to determine what the optimal code was for that particular kind of system.

Hi Walter,

Thank you sincerely for patient reply.
