说明：  5、绘制散点图。 对发射和接收信号利用scatterplot函数可显示信号星座图的样子及噪声对信号造成的失真程度。在该图中，横轴代表了信号的同相分量而纵轴代表了正交分量。下面的代码还利用了 对接收信号利用modem.deqammod对象的demodulate方法进行解调。解调结果为包含0到15之间整数的列向量。 (5, draw a scatter plot. The transmitted and received signals can be displayed using a function of the degree of distortion scatterplot like and noise signals caused by the signal constellation of FIG. In this figure, the horizontal axis represents the in-phase component signal and the vertical axis represents the quadrature component. The following code is also used to demodulate the received signal using the method of demodulating modem.deqammod object. Demodulation result is an integer from 0 to 15 comprising a column vector.)

This tutorial deals with the rootfinding, interpolation, numerical differentiation and integration and numerical solutions of the ordinary differential equations.

最短路这个说明倒不是说明函数的功能，只是声明一下函数中出现的问题。 shortest()函数没有问题，在secshortest中我希望只得到一条次短路（或几条roadcost()值相同的次短路），结果却出来好几条，我仔细检查了一下程序，应该没有什么问题。 因此在使用时，要得到次短路，只能用roadcost()函数分别求一下各条路的权重和，找到最小的。 有些奇怪 (short path)
