  Models on logarithmic lattices have recently been proposed as an alternative
approach to the study of multi-scale nonlinear physics. Here, we introduce
LogLatt, an efficient MATLAB library for the calculus between functions on
multi-dimensional logarithmic lattices. The applicabilities include common
differential operators, norms, and convolutions, and operate as MATLAB function
handles, so their implementations result in elegant and intuitive scripts.
Particularly, when applied to dynamics, users may code the governing equations
exactly as they are mathematically written. We give codes and results for some
problems of fluid flow as examples of application.
