MathBlackBoard as User Interface of Computer Algebra Systems
MathBlackBoard is a Java program based on the blackboard applet. We can use the blackboard applet with GUI operations. The blackboard applet has simple kernel as computational engine.
In this paper, we describe improvements of MathBlackBoard. MathBlackBoard is reconstructed as a set of objects. We have improved GUI operations of MathBlackBoard. And, we have added new functions which use some computer algebra systems as computational engine.
