""" sasmodels ========= **sasmodels** is a package containing models for small angle neutron and xray scattering. Models supported are the one dimensional circular average and two dimensional oriented patterns. As well as the form factor calculations for the individual shapes **sasmodels** also provides automatic shape polydispersity, angular dispersion and resolution convolution. SESANS patterns can be computed for any model. Models can be written in python or in C. C models can run on the GPU if OpenCL drivers are available. See :mod:`generate` for details on defining new models. """ __version__ = "0.9"
