idl2matlab under Windows, Mac or Linux automatically partially converts IDL code to MATLAB / Octave code.
Alternatives to converting IDL code
I avoid converting code 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 through version 8.
Call IDL from Python
Call GDL from Python
from Python, simply
import GDL see PYTHON.TXT
Partial conversion of IDL to Matlab
Here’s the partial automatic converter of IDL code to Matlab code.
- 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.
