这是一个马乐土科夫-GM（1，1）的程序代码，一般用于预测，对于短期预测非常有效(This is a horse paradise Cove-GM (1,1) of the code, generally used for prediction, is very effective for short-term forecast)

When doing optimization, GA algorithm was initially selected, but the instability of the GA (or local optimization) is really frustrating, before and after the resulting difference can at times reach more than 30 , at that time due to time reasons, I chose to optimize 1000 times, then the minimum value of the most optimal solution. Although the problems are solved, but an academic, this style of running is pretty embarrassing. So, I downloaded a GA-PSO algorithm, try using the combination of GA and PSO optimizing strategies, results algorithm issues, efficiency and good. I downloaded the original algorithm, there is a problem is that it is aimed at all upper and lower limits of the design variables are the same, so I modified the program and improvements, you can now deal with upper and lower limits of the inconsistency problem and fix the bug. Now, program modifications, and share, hoping to be useful to you

SImulation of real time traffic signals

This is a MATLAB Simulation for obtaining conduction and switching losses in Three-Phase OHSW(optimized harmonic stepped wafeform) cascaded 9-level inverter.The simulation has been done in several SUBSYSTEMS.The first one produces switching functions based on OHSW.The second one is the 9-level inverter model.the third and fourth obtain load and switching devices currents respectively.The fifth and sixth obtain switching and conduction losses.
