这是一个关于垂直腔半导体光放大器（VCSOA，微腔光放大器的一种）中的双稳态曲线计算程序，用Matlab语言写成，可执行。程序是根据VCSOA中的速率方程（Rate Equation）编写的。从曲线上可以看出随着输入功率Pin的变化VCSOA的输出功率Pout的双稳态曲线，是进一步研究该问题的基本素材之一。(This is a computation program for calculating the bistability activity of the vertical cavity semiconductor optical amplifier, which is based on the rate equation in VCSOA. This code is a basis for further investigating other activities in VCSOA related to bistability. )

说明：  一个长信号进行分析时，可能需要对信号分段，本程序提供一种分段方法(When a long signal is analyzed, it may be necessary to segment the signal)
