中文说明：Pisarenko谐波分解算法,真的是一个好程序，实现用SDRAM运行nios，同时用SRAM保存摄像头数据，比较了软阈值，硬阈值及当今各种阈值计算方法,旋转机械二维全息谱计算的实用例程，最终的权值矩阵就是滤波器的系数。
English Description：
Pisarenko harmonic decomposition algorithm, really is a good program, realized by using SDRAM operation NIOS, also with SRAM save camera data and soft thresholding, hard threshold and the current method of calculating the various thresholds, rotating machinery two-dimensional holographic spectrum calculation of utility routines, the final weight matrix is that of the filter coefficients.
