以MATLAB程序开发一个后处理器，产生N个样本的输入数据的直方图、PSD估计及自相关。运行后处理器的任何必要参数都通过参数文件输入，有后处理器读取。将零均值、单位方差的高斯过程的N=5000个样本通过巴特沃斯滤波器产生N个样本，这里的滤波器的截止频率为0.2fN，其中fN为奈奎斯特频率，用这样的样本测试后处理器。-MATLAB program to develop a post-processor to generate a histogram of N samples of input data, PSD estimates and autocorrelation. Any necessary parameters processor running through the parameter file input, there is a post-processor to read. The zero-mean, N unit variance Gaussian Processes = 5000 samples produced by N samples Butterworth filter with a cutoff frequency where the filter is 0.2fN, where fN is the Nyquist frequency, the use of such samples test post-processor.
