Which computer programming language are MATLAB R2015b and R2016b written in?

Answer 1

[James Tursa]

Java for the interface, C++ for computational library stuff, and some 3rd party libraries for some of the matrix algebra BLAS and LAPACK stuff. The BLAS and LAPACK libraries use a Fortran function/subroutine interface (e.g., see www.netlib.org) but are probably written in C/C++ or assembly.

And, some of the supplied functions are written in ... MATLAB.

Answer 2

[Meade]

Matlab is mainly written in Java (interface etc). Many of the operations are written in C or C++. The matrix stuff is based on some pretty old Fortran I think. https://en.wikipedia.org/wiki/MATLAB

[Walter Roberson]

It would not be C#, as that relies too heavily on .NET

[Meade]

True! I mis-typed.

[Tyler Shepard]

I believe the matrix math is based on BLAS which has routines written in assembly specified for x84 and AMD64 processors. The rest is written in C(++) and Java, for back end computations, and symbolic algebra objects (object oriented programming).

MATLAB calls LAPACK and BLAS https://www.mathworks.com/help/matlab/matlab_external/calling-lapack-and-blas-functions-from-mex-files.html

LAPACK is written in Fortran . http://www.netlib.org/lapack/

BLAS has a couple of different implementations. For Windows it is included with LAPACK http://www.netlib.org/blas/

MATLAB is also known to call upon Intel's MKL https://www.mathworks.com/matlabcentral/answers/71553-amd-vs-intel-mkl-dll-vs-acml-dll-and-blas-spec-help . The official description https://software.intel.com/en-us/mkl does not say what language MKL is written in; Wikipedia says C/C++ and Fortran.
