STFT

代码说明：

  信号的短时傅立叶变换，paper2_2_1为主程序，仿真不同窗长下短时傅立叶变换的时频聚集度。stftxz为修正的短时傅立叶变换。(Short-time Fourier transform signals, paper2_2_1 main program, the simulation under different window length short time Fourier transform of the frequency of aggregation. stftxz to correct short-time Fourier transform.)
