学习abaqus子程序umat的绝好例子，权威专家编写(Learning excellent examples of abaqus umat subroutine, leading experts to write)

该程序主要对非球面镜进行波面拟合，首先读入采集的离散面型数据，可以是从椭圆曲面，抛物面等采样得到，也可以是通过其他软件计算得到的数据。然后将数据用Zernike多项式进行拟合得到非球面表达式各项的系数。(The program on the aspheric wavefront fitting, first read into a collection of discrete surface data can be Sampling from the oval surface, the paraboloid, can also be calculated data obtained by other software. However After aspherical expression obtained by fitting the data with Zernike polynomials coefficient.)
