Low rank approximations for the DEPOSIT computer code
arXiv:1403.4068 · doi:10.1016/j.cpc.2014.06.012
Abstract
We present an efficient technique based on low-rank separated approximations for the computation of three-dimensional integrals in the computer code DEPOSIT that describes ion-atomic collision processes. Implementation of this technique decreases the total computational time by a factor of 1000. The general concept can be applied to more complicated models.
