+## Matlab bindings
+
+_Experimental_: eos includes Matlab bindings for the `fit_shape_and_pose(...)` function, which means the fitting can be run from Matlab. Set `-DGENERATE_MATLAB_BINDINGS=on` when running `cmake` to build the required mex-file and run the `INSTALL` target to install everything. (Set `Matlab_ROOT_DIR` to point to your Matlab directory if it's not found automatically). More bindings (e.g. the MorphableModel itself) might be added in the future.
+
+Go to the `install/eos/matlab` directory and run [`demo.m`](https://github.com/patrikhuber/eos/blob/master/matlab/demo.m) to see how to run the fitting. The result is a mesh and rendering parameters (pose).
