该程序为matlab环境下程序，用于分形研究，用锯齿波生成元构成的分形(有点像两只青蛙)(The program for the matlab environment procedures for fractal research, with sawtooth generator constitute the fractal (a bit like a frog 2))

说明：  一个bp网络拟合非线性模型的例子，参考了李国勇书中的公式(A bp network nonlinear model fitting example, with reference to the book' s formula Li Guoyong)

以前使用matlab和vc混合编程都使用的是先将m程序用mcc转化成dll，再在vc中调用 的方法。这种方法对比较复杂的m文件很方便，但是对一些小的程序，如曲线可视化、计算矩阵特征值等，对这些只需要一两行代码的小程序，再使用dll就得不偿失了。经过试验后，发现可以直接在C++程序中调用matlab c/c++ math & graphic library的函数。(before using Matlab and vc mixed programming using the first procedure used mcc m into dl l, then vc call method. This method of complex documents m very easy, but for some minor procedures, such as curve visualization, matrix eigenvalue calculation, and so on, these are just two lines need a small procedure code, reuse dll on the loss outweighs the gain. After testing, can be found directly in the C Programming Calling Matlab c/c math)

三相电压型PWM逆变器的数学模型和主电路设计 完整三相电压型PWM逆变器模型 双闭环 (Mathematical model of three-phase voltage-type PWM inverter main circuit design and complete a three-phase voltage-type PWM inverter model dual-loop)

OFDM系统的简单代码，便于初学者理解，设置了N=128个信道，传送1,0的随机数，并加入fading和AWGN noise(OFDM system simple codes, for beginners to be understood that the channel 128 is provided, fading and AWGN noise added)

This function rotates the x-tick labels on a plot. An arbitrary angle can be specified for the text and the label justification adjusts appropriately to ensure the labels lie below the ticks.
