说明：  将一个文件中的非标点符号字符查找出来，放入到一个新文件中(A file of non-punctuation characters to find out, put into a new file)

完成智能天线的T程序仿真，通过仿真可以输出天线的MUSIC算法的结果(Smart antenna to complete the T process simulation, simulation can be output through the antenna of the results of the MUSIC algorithm)

应力应变计算的有限元程序。上课的时候用matlab写的一个代码，其中的刚度矩阵计算，刚度矩阵整合和载荷矩阵计算，都具有通用性，可以参考用于有限元程序设计。(stress and strain of finite element program. When the class was using a Matlab code, which the stiffness matrix, Integration stiffness matrix and load matrix, are generic and can reference for finite element program design.)

The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):
