%X As issues of low calculation speed,out of memory,and the calculation length of FFT seriously affecting the capacity of time-frequency resolution,etc.,happened during calculating of frequency decomposition on large-capacity seismic data.In order to overcome those issues,this paper improved MATLAB time-frequency toolbox's time-frequency algorithm,which based on the discrete short time Fourier transform,implemented the algorithm by applying of Fortran language in microcomputer programming.The theory calculatio...
