Analytica is a web app to solve systems of linear equations using different algebraic and numerical methods. Not only showing the final solution, but all the steps involved to get that solution.

Background One in seven households in England live in accommodation not meeting housing quality standards. Low-quality ...

Abstract: A typical recurrent neural network called zeroing neural network (ZNN) was developed for time-varying problem-solving in a previous study. Many applications result in time-varying linear ...

Abstract: This article investigates the stability of continuous-time switched linear systems with dwell-time constraints. A fresh insight into this established problem is provided via novel stability ...
