该程序提供了多种参数的双指数脉冲函数的波形及其频谱分解图，要注意的是作图时坐标比例尺的调整。程序中给出的是1.2/50μs和0.7/60ns两种波形可直接使用的坐标比例尺。 在MATLAB5.0下就能工作。 (The program provides a wide range of parameters of double-exponential pulse function waveform and its spectral decomposition diagram, it should be noted that when mapping coordinates scale adjustments. Procedure is given in 1.2/50μs and 0.7/60ns two waveforms can be directly used the coordinates of scale. Will be able to work under in MATLAB5.0.)
