这个MATLAB例程是系统误码率变化仿真(The MATLAB routine changes in the system simulation of bit error rate)

编码是在MATLAB下编写的，可以在MATLAB上直接运行，我没有在分类中找到MATLAB，所以选择了c++，希望管理员能分下类。这款编码是计算水准测量中计算条件平差的。(The code is written in MATLAB, you can run directly in MATLAB, MATLAB, I did not find in the classification so chose c++, I hope that the administrators in the next class. This code is calculated in the calculation leveling adjustment of condition equations.)

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):
