PIETOOLS is open-source, so feel free to use it as an interface to your own software. If you are into the retro vibe, there are still lots of fun things you can do with PIETOOLS, like declaring PDEs, DDEs, and DDFs converting between representations, finding minimal representations, and playing with integral inequalities. What if I don't like PIE?Įveryone likes PIE! But really, that's cool.
The solutions are one-to-one, only the tools used for representation have improved. The PIE representation of a PDE/DDE/DDF is exact. However, let us assure you that using PIEs is completely safe. You may have been hurt in the past by people wrecking your lovely PDE/DDE/DDF using such barbaric tools as approximation via discretization, projection, mollification, regularization or Pade. Now, you may be wondering if you are going to lose anything by switching your PDE/DDE/DDF to a PIE. This feature makes PIEs the representation of choice if you want to do anything computational with your beam equation, network model, reaction-diffusion equations, et c.
The cool thing about PIEs is that, unlike PDEs and DDEs (which have lame boundary conditions, unbounded operators, and continuity constraints), PIEs are defined by the very slick linear algebra of 3/4 PI operators. PIE stands for Partial Integral Equation and is an alternative representation for many commonly encountered classes of systems, including Ordinary Differential Equations (ODEs), Partial-Differential Equations (PDEs), Delay Differential Equations (DDEs), and Differential-Difference Equations (DDFs).

How to Get Started with PIETOOLS What is a PIE? Introduction to PIETOOLS Youtube Video Read the Guide: By default the LPIs are solved using SeDuMi. The interface is inspired by YALMIP and the program structure is based on that used by SOSTOOLS. PIETOOLS canīe used to define 3-PI or 4-PI operators, declare 3-PI or 4-PI operators variables (postive semidefinite or indefinite), add operator inequality constraints, and solve LPI optimization problems. PIETOOLS is a free MATLAB toolbox for formulatingĪnd solving Linear PI Inequalities (LPIs) programs.
