Add NFSOFT Matlab class #76

Closed michaelquellmalz closed 6 years ago

michaelquellmalz commented 6 years ago

This adds a Matlab handle class for the NFSOFT module just like for other modules.

This changeset also includes a small reduction of memory usage of the NFSOFT. Previously, the vectors x and f were stored twice and copied during the precomputation (for x this includes also a renormalization and reordering). Now, the user can set the pointers to the same value to store the vectors only once. This is automatically done in the MEX interface.
