PeriodicMatrices.jl provides the basic tools to handle periodic time-varying matrices. This package is the basis for developing the PeriodicMatrixEquations.jl and PeriodicSystems.jl packages. For a real periodic matrix A(t) with period T, the dependence of the time variable t can be either continuo…

Congrats for making your work available to the community! Much appreciated. Please apologize for being only poorly literate on periodic matrices. I do, however, wonder how PeriodicMatrices.jl implements operations on truncated harmonic series. This curiosity stems from the fact that we wish to imp…

Periodic matrices can be represented simply as function matrices or symbolic function matrices, in which cases there is no information stored about the used number of harmonics. However, the HarmonicArray representation stores all harmonic terms (packed in a complex 3-dimensional array) and yes, ope…

Sincere thx to both. Much appreciated.
