MATLAB 的应用范围非常广，包括信号和图像处理、通讯、控制系统设计、测试和测量、财务建模和分析以及计算生物学等众多应用领域。附加的工具箱（单独提供的专用 MATLAB 函数集）扩展了 MATLAB 环境，以解决这些应用领域内特定类型的问题。(MATLAB very wide range of applications, including signal and image processing, communications, control system design, test and measurement, financial modeling and analysis, and computational biology and many other applications. Additional kit (available separately dedicated set of MATLAB functions) extend the MATLAB environment to solve these application areas certain types of problems.)

Eigenfunctions of integrable planar billiards are studied — in particular, the number of nodal domains, ν of the eigenfunctions with Dirichlet boundary conditions are considered. The billiards for which the time-independent Schrö dinger equation (Helmholtz equation) is separable admit trivial expressions for the number of domains. Here, we discover that for all separable and nonseparable integrable billiards, ν satisfies certain difference equations. This has been possible because the eigenfunctions can be classified in families labelled by the same value ofm mod kn, given a particular k, for a set of quantum numbers, m, n. Further, we observe that the patterns in a family are similar and the algebraic representation of the geometrical nodal patterns is found. Instances of this representation are explained in detail to understand the beauty of the patterns. This paper therefore presents a mathematical connection
