 - **CurveLab**: In order to use `joCurvelet2D` or `joCurvelet2DnoFFT` operators, you need to obtain *CurveLab-2.1.2-SLIM*, a SLIM extension to *CurveLab-2.1.2*. The tarball of this extension is available from [curvelet.org](http://www.curvelet.org) under [Software](http://www.curvelet.org/software.html) tab. The installation instructions are included in the tarball of *CurveLab-2.1.2-SLIM*. Note, that CurveLab is free only for academic use and requires registration.

If you have configured `PyCall` with your own python environment you can install `PyWavelets` via `pip install --upgrade PyWavelets`.
