Related: call Matlab from Python
oct2py is a wonderful way from Python to use Matlab/Octave
.m code without having Matlab.
As the name implies,
oct2py uses GNU Octave to run most
.m code out there (that doesn’t call proprietary Matlab toolboxes).
Assuming you already have Octave installed, whether via
apt install octave
or via compiling Octave, then install
oct2py in Python by from Terminal:
pip install oct2py
Load Octave packages from Python
When using Oct2Py, you load a package with
from oct2py import Oct2Py oc = Oct2Py() oc.eval('pkg load signal') b = oc.fir1(11,[0.01,0.5])
That example uses “Matlab”
fir1() function from Python, perhaps to compare with
Octave Packages explained
To speed up Octave loading and enhance stability and development cycles, a lot of Octave functionality is split off into packages.
These package are loaded by simple
For example the Octave
signal package is loaded in a
.m file by:
pkg load signal
To keep Matlab compatibility, I actually use in the
try pkg load signal end
This way, Matlab ignores the Octave-specific command.
