Matlab编程实现FFT变换及频谱分析的程序代码（适合初学者加强理解）。（1)用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图；(2)进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选；(3)做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱；(4)用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图。(Matlab codes for FFT Understanding which contains sine wave,rectangular wave and the reletaed frequency spectrum figure about MSE,Log,IFFT and so on.)

说明：  Matlab code advanced DSP lab

说明：  主要是通过GA和PSO的全局搜索能力，用于改进BP网络的权值阈值(It is mainly used to improve the weight threshold of BP network)
