You don’t have to translate/map everything (just use, or read its mapping if you want to map):

You can also just call to (or from) MATLAB:

> Inspired by this [recent discussion](https://discourse.julialang.org/t/calling-julia-from-matlab-the-smoothest-path-to-sneak-julia-into-a-company/64845) regarding the state of calling Julia from MATLAB, I have put together a package to try to resolve some of the issues faced by previous approaches: [JuliaFromMATLAB.jl](https://github.com/jondeuce/JuliaFromMATLAB.jl). Please scroll down to see the Quickstart guide, pasted here from the package’s README for convenience. In particular, I have chosen to avoid trying to keep up with the MATLAB Mex C/C++ interface. Instead, communication between MATLAB and Julia is performed by writing to temporary .mat files. This…

You CAN also call to Octave, the MATLAB clone language, then you have standard functions, lose out on toolboxes. But I couldn’t use the library for that at the time, and it’s still unchanged for 4 years now.

But I could call Python (then with PyCall, now would use PythonCall), and to Octave from it… Calliing Python in-process, not to Octave from it, it still works. And I had to disable OpenBLAS threading with an env var, do get around a bug.

This might help you migrate (I did in stages), or actually not migrate, just use MATLAB code.

There IS a MATLAB code translator available online, but it doesn’t handle all syntax, nor semantic differences:

> Convenient online tool automatically translates MATLAB source code into Julia, so you can move on to the more interesting task of parallelizing your code.
