JuliaLAB

Embedded Julia in MATLAB

How it works

JuliaLAB is a MEX library that links against libjulia. It uses Julia's and MATLAB's C APIs to call functions, convert and pass data between languages, and handle exceptions.

How to use

1. Either add JuliaLAB/src to the MATLAB path or change to that directory.
2. Run julia_compile(<path_to_julia-config.jl>).
3. Run julia_eval(<str>) or julia_call(<function_name>, arg1, arg2, ...)

Caveats

All MATLAB variables are converted to Julia arrays of at least 2 dimensions (as this is how MATLAB arrays are represented).

The library is largely incomplete at the moment, but more features are coming. Currently the functions will:

1. Evaluate the function or string.
2. If a Julia exception occurred, throw a MATLAB exception.
3. If the result of the evaluation was a Float64, print it and return true, else return false.

Current major bug

There is currently a major bug that causes MATLAB to crash sometime after running these functions. I would appreciate your help! See this thread and this gist.

Requirements

• Julia 0.3+
• MATLAB (tested on 2012b, but should work with older versions)
