MATLAB程序关于自动处理txt文本内的数据，将数据转换成矩阵型计算后导出得出新数据的TXT文本，内含全英文实验报告-The whole program is developed to deal with the display and processing of material properties of a gas. The material properties of an example gas is given in a text file called "ass1data.txt" and the data in the file will be read into a Matlab matrix. The data in the matrix will be used in different modules and solve different problems such as, display a single value of a material property at a single temperature,　display the material properties in individual figures or write new date about the material properties into a new file.
