建立几何畸变模型，实现畸变矫正。通过获取模板图像的坐标值，求取变换模型参数，求出变换多项式的系数。-IMAGECORRECT M-file for imageCorrect.fig IMAGECORRECT, by itself, creates a new IMAGECORRECT or raises the existing singleton*.

300HZ 采样率下，50、60HZ陷波器及8HZ高通多项式实现。画出原始数据及滤波后数据并画出相应频谱-50/60HZ notch filter of the matlab program.Plot raw data and filtered data and corresponding Spectrum

MATLAB,多项式函数拟合,使用polyfit命令，可以拟合出二维图形。-MATLAB, polynomial fitting function, use the polyfit command, you can fit a two-dimensional graphics.
