中文说明：MATLAB 是美国MathWorks公司出品的商业数学软件，用于算法开发、数据可视化、数据分析以及数值计算的高级技术计算语言和交互式环境。MATLAB和Mathematica、Maple并称为三大数学软件。它在数学类科技应用软件中在数值计算方面首屈一指。线性规划是运筹学中研究较早、发展较快、应用广泛、方法较成熟的一个重要分支，它是辅助人们进行科学管理的一种数学方法。它是运筹学的一个重要分支，广泛应用于军事作战、经济分析、经营管理和工程技术等方面。为了方便求解线性规划问题，我们用Matlab开发了一个可视化的求解线性规划问题的程序。
English Description：
Matlab is a commercial mathematical software produced by MathWorks company of America. It is a high-level technical computing language and interactive environment for algorithm development, data visualization, data analysis and numerical calculation. Matlab, Mathematica and maple are called three mathematical softwares. It is second to none in numerical calculation in the application software of mathematics science and technology. Linear programming is an important branch of operations research, which is studied earlier, developed faster, widely used and has mature methods. It is a mathematical method to assist people in scientific management. It is an important branch of operations research, widely used in military operations, economic analysis, management and engineering technology. In order to solve the linear programming problem conveniently, we developed a visual program to solve the linear programming problem with MATLAB.
