# 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.

Prereqs:

`apt install make git g++`

Compile LibSVM

```
git clone https://github.com/cjlin1/libsvm
cd libsvm
make
```

Creates executables `svm-train svm-predict svm-scale`

.
Compile the Matlab/Octave and Python modules, for which the API is similar.

Compile LibSVM Matlab/Octave module

`cd libsvm/matlab`

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

)

`make`

which creates a few `.mex`

files.
See the `matlab/README`

for examples of using LibSVM from Matlab and Octave.

Compile LibSVM Python module

```
cd libsvm/python
make
```

See the `python/README`

for examples of using LibSVM from Python.
