Development of Personal System of Symbolic and Algebraic Computation in the Field of Ship Hydrodynamics

为船舶流体力学领域的科学家和学生开发了一个符号和代数计算的个人系统。解析解的方法有助于明确地了解流动的重要行为，特别是在奇异点附近的流动行为和解的参数依赖性，即使已经完成了计算流体力学。然而，一般来说，他们很难也不愿意准确地操作公式。该系统对船舶流体力学理论教学有一定的辅助作用。该系统是一个增强的muMATH-83^ tm>系统，源代码是Soft Warehouse开发的原始系统的三倍。宿主语言是musimp -87^<tm>，但是大部分函数是用表面语言muSIMP-83^<tm>编写的。具体实现如下。muSIMP-83语言的扩展和漂亮的打印程序2。窗口管理器使用的简易输入系统。多元多项式的展开与分解。常微分方程例程的推广。结石加固复杂的数值函数；7.2二维和三维图形函数

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
