Install LibSVM in Matlab, GNU Octave and Python

Matlab and Octave are popular for machine learning prototypes due to their easier to learn (vs. R) interface. Python via scikit-learn is also a top choice for machine learning. Here’s how to install LibSVM for Matlab and GNU Octave.

  1. prereqs:
   apt install make git g++
  1. Compile LibSVM
   git clone

   cd libsvm 


Creating executables svm-train svm-predict svm-scale. Now compile the Matlab/Octave and Python modules, for which the API is similar. 3. Compile LibSVM Matlab/Octave module

   cd libsvm/matlab

Open Matlab or Octave, and from that internal Terminal, type (this uses make.m)


which creates a few .mex files. See the matlab/README for examples of using LibSVM from Matlab and Octave. 4. Compile LibSVM Python module

   cd libsvm/python


See the python/README for examples of using LibSVM from Python.
