用FIR数字滤波器实现对数字信号的滤波,使设计带阻滤波器，计算相位延迟并绘制滤波后波形序列(FIR digital filter realized with digital signal filtering, band stop filter to design, calculate and draw the filtered phase delay waveform sequence)

车辆道路谱时域频域平均功率谱分析matlab程序(Road vehicles, the average spectrum of time domain frequency domain power spectral analysis matlab program)

Three test programs provided. These programs just set the matrices to be diagonalized, then call the function repeatly. After each call it printout the transformed matrix, the diagonalizing matrix and the criterion and its decrease.

Fminsearch does not admit bound constraints. However simple transformation methods exist to convert a bound constrained problem into an unconstrained problem.
