通过电子Smith圆图实现L型阻抗匹配，分析L型阻抗匹配网络的匹配种类和计算L、C的值。(L impedance matching was achieved through electronic Smith chart, analysis of l-shaped impedance matching network of matching types and calculating the value of L, C. )

通过修改输入excel文件中的铺层信息及材料属性，计算层合板的等效模量及极限强度，并绘制应力沿厚度方向的分布图(The equivalent modulus and ultimate strength of the laminates are calculated by modifying the information and material properties of the laminates inputted into excel files, and the stress distribution along the thickness direction is plotted.)

Gauss Elimination Algorithm is used to solve linear equations in the form Ax=B, find rank of matrix and to find inverse of matrixes. The program is done in matlab platform.

This is not a Matlab tutorial. This is just a list of tricks.
