数字信号处理的傅里叶变换与逆傅里叶变换经典实现，非常具有实用价值-Fourier transform and inverse Fourier transform of digital signal processing to achieve the classic, very practical value

MATLAB实现短时傅里叶变换，短时傅里叶逆变换。直接配置好参数就可以用，实用性强。(MATLAB implementation of short time Fourier transform, short time Fourier inverse transform. Direct configuration of parameters can be used, practically.)

可轻松实现短时傅里叶变换及对应逆变换，可更改程序内部窗函数，自行选择合适窗函数进行分析(Short-time Fourier transform and corresponding inverse transform can be easily realized. The internal window function of the program can be changed and the suitable window function can be selected by onesel
