Abstract

We present a simple method for quasilinearity (QL) analysis of differential-algebraic equations (DAEs). It uses the signature matrix and offsets computed by Pryce’s structural analysis and determines if a DAE is QL in its leading derivatives. Our method is suitable for an implementation through operator overloading or source code translation.
