IndexFunArrays.jl | Fun with indices (and functions on them)
Felix Wechsler, Rainer Heintzmann

IndexFunArrays.jl provides a convenient way to work with index dependent functions.
In signal processing it often occurs that an array needs to processed (e.g. applying a window functions) depending on the indices. One could write for loops processing the data in-place. However, a different technique is to create arrays which do not allocate memory but instead generate the desired value when accessed.
