Sparse

OUT=SPARSECONV(X,F) efficiently computes the convolution of the (sparse) input X with the (sparse) filter F. Speed gain can be extremely high in case both X and F are long sparse vectors.

Inspired by and improves on the Sandia National Labs sparse tensor toolbox http://csmr.ca.sandia.gov/~tgkolda/TensorToolbox/. See src_test for example use

Implements sparse triangular solve as a MEX function, thus is much faster than . Useful for iterative methods (to apply a factored preconditioner).
