This function takes the n time domain samples (real or complex) and finds the psd by taking (fft/n)^2. The two sided spectrum is produced by shifting the psd The array freq provides the appropriate frequency values for plotting purposes. By taking 10*log10(psd/max(psd)) the psd is normalized values beow 60db are set equal to -60db

bp for matlab and can be train each oder

矩形检测,基于MATLAB的利用霍夫变换，自己弄的，很实用(rectangular detection)

粒子群算法之一，可在matlab中运行，分析一些函数的最优化问题(a kind of particle swarm, can be used in matlab)
