中文说明：基于matlab GUI界面设计,该函数用来计算任意函数的一阶偏导数(数值方法),isodata 迭代自组织的数据分析，采用了小波去噪的思想，计算时间和二维直方图,详细画出了时域和频域的相关图。
English Description：
Based on Matlab GUI interface design and the function used to calculate any function of the first order partial derivative (numerical method), ISODATA iterative self organizing data analysis, the idea of using wavelet denoising, computational time and two-dimensional histogram, with painting out of the time domain and frequency domain correlation diagram.
