求解椭圆型，双曲型和抛物型偏微分方程的matlab代码(Solve the elliptic, hyperbolic and parabolic partial differential equations matlab code)

首先在m脚本文件canshuo.m中输入节点个数和路径权重，在命令窗口中输入canshu，用s=12,e=10的格式输入要求的起止点，再输入main即可得到两点之间的路径和长度。(M script file canshuo.m first enter the node number and the right path lies in the command window enter canshu, with s = 12, e = 10 The format of the input requirements of the start and end points, and then enter the main between two points can be obtained path and length.)

有均匀线阵的CRB曲线，抑制载波型差分相位调制，能量熵的计算。( There ULA CRB curve, Suppressed carrier type differential phase modulation, Energy entropy calculation.)

方波函数的傅里叶展开-自己编的小程序，希望能有所帮助(Square wave function )

在OFDM系统 中，宽带信道被分割相互重叠的窄带子信道，如果各子信道 的带宽比信道的相干带宽要小，那么信号传输就有可能在无 频率选择性衰落或者平坦衰落的信道进行。(In OFDM system The wideband channel is divided into narrowband sub-overlapping, if each sub- The bandwidth is less than the coherence bandwidth of the channel, the signal transmission is possible without Frequency selective fading or flat fading channels.)

this is the code about display and plot average
