IDL2Matlab is a program that automatically partially converts IDL code to MATLAB / Octave code. However, this project appears to be abandoned; there haven’t been updates in a few years.
Alternatives to converting IDL code
I avoid converting code if possible, because it can introduce subtle errors. Here are some alternatives allowing you to run the unmodified IDL code for free.
free GDL (GNU Data Language)
If the issue is that you don’t want to install IDL, try using free GDL that is compatible with IDL.
Call IDL from Python
Call GDL from Python
from Python, simply
import GDL see PYTHON.TXT
This procedure is for Linux.
Download prereqs and code:
apt install libbison-dev flex git clone https://github.com/farhi/idl2matlab cd idl2matlab
Prepare to install in your
CFLAGS = -g -fno-stack-protector
Compile and install under
make && make install
The MATLAB code that
idl2matlab produces uses a sort of cumbersome Matlab script that calls its own Matlab functions to do common tasks.
The converted code can be further optimized.
Still, probably easier than doing it all manually.
You’ll need to know basics of IDL, like what
randomu mean in Matlab.
Not plug and play, but not totally manual.
