A personal system of symbolic and algebraic computation is developed for scientists and students in the field of ship hydrodynamics.Analytical method of solution is useful to know the significant behavior of the flow especially near singular points and also the parameter dependency of the solution explicitly, even if Computational Fluid Dynamics was accomplished. However, generally speaking, it is difficult and reluctant for them to manipulate formulas exactly. This system is an aid to education of theoretical ship hydrodynamics.This system is a reinforced muMATH-83^<tm> system which source code is three times as many as the original one developed by The Soft Warehouse. The host language is muLISP-87^<tm>, however the most of functions are written in muSIMP-83^<tm> the surface language. Following are implemented.1. Extension of muSIMP-83 language and pretty print routine2. Easy input system utilized by the window manager3. Expansion and factorization of multi-variate polynomial4. Extension of the routine for ordinary differential equations5. Reinforcement of calculus6. Complex numerical functions7.2D and 3D graphic functions
