可以进行平面拟合，基于matlab语言-拟合

本程序实现了基于最佳维纳滤波器的盲解卷积算法。维纳滤波将地震子波转换为任意所需要的形态。例如，像反滤波一样，可以设计维纳滤波器将地震子波转换为尖脉冲。但维纳滤波不同于反滤波，它是在最小平方的意义上为最 佳。基于最佳纳滤波理论的滤波器算法是人们熟知的维纳一莱文逊(Wiener—Levinson)算法。本程序提供了五种期望输出：零延迟尖脉冲；任一延迟尖脉冲；时间提前了的输入序列；零相位子波；任意期望波形。(Wiener—Levinson algorithm used in wiener filter. matlab with detailed note in Chinese.)
