Visual matrix calculator for undergraduate students

We propose a visual matrix calculator, VISMAT, which has a basic matrix computation function and performs operations on a matrix. A user of VISMAT can perform a matrix computation and matrix operation on a window as if computing matrix calculations using just a notebook. VISMAT is implemented in Java, so it can be used both as a frame based application and as an applet based application. The matrix element may be a simple symbolic expression such as a fractional number. VISMAT has been developed mainly for educational purposes. We want to provide an educational tool for undergraduate students who study algorithms of basic matrix computations. As there is a marked decline in studentsʹ ability to do mental calculations, we strongly believe that this will provide an environment in which students can engage in various problem-solving exercises without unreasonably tedious labor.
