Matlab实现的曲面拟合算法，给定一组坐标（x,y,z） 拟合成函数 （x,y,z 为行向量），由最小二乘法得到关于输入量的多阶矩阵。当p，q 越大时，拟合的函数与原数据的方差越小，可以做个图看出来。-Matlab realization of the surface fitting algorithm, given a set of coordinates (x, y, z) to be the synthesis function (x, y, Z for the line vector), the least squares method to get the input of the amount of the multi- order matrix. When Q, P is larger, the smaller the variance of the function and the original data, you can make a picture to see.
