I believe one of the strongest features in MATLAB is their symbolic math toolbox, and it might be really handy if we could switch from MATLAB to open-source alternatives. In Python, this is SymPy.

Abstract: This paper demonstrates convenient use of freely available Polmat library for computations with transfer function models of multidimensional systems within Matlab environment. Polmat ...

(what passes for credentials: D.Phil in theoretical physics, particularly numerical simulation, and undergraduate physics teacher for a few years) MatLab and Octave are very similar (Octave is an open ...

Abstract: In this article, a synthesis methodology for analog circuit design is presented. This methodology utilizes symbolic math tools to systematically and exhaustively search for candidate analog ...
