Mppt_sfunction

有关matlab的基本运算函数，基本绘图指令（平面和立体），pdf格式的matlab循序渐进是一本对初学者很有帮助的书(Related to basic computing matlab function, basic drawing commands (plane and three-dimensional), pdf format matlab is a gradual one pairs of helpful books for beginners)

The toolbox provides functions to: - encode dual quaternions: a point position, velocity, a line position, velocity, a rotation, a translation, a screw,... - do operations on dual quaternions: the dual quaternion multiplication, the dual quaternion conjugates, the inverse,... - retrieve parameters from a dual quaternion: finding the parameters of a rotation dual quaternion, or a screw dual quaternion,... - easily going back and forth between Fick rotation coordinates, 3*3 rotation matrices, rotation dual quaternions, angular vector

九点差分格式，精度比五点差分要高，对于实现有限差分，是一个重要的程序(Nine-point difference scheme, the accuracy than the five-point difference is higher, for the realization of finite-difference, is an important procedure)

《空间谱估计原理与算法》多重信号分类法估计matlab源代码(" Space Spectrum Estimation Principle and Algorithm" multiple signal classification method estimates matlab source code)

牛顿方法优化算法可以用于多方面的例子，很不错。(Newton method for optimization algorithm can be used for a wide range of examples, very good.)

这里面有很多的电力电子、电机控制系统的simulink仿真模型(There are a lot of power electronics, motor control system simulink simulation model)

说明：  由于matlab提供了一些很有用的计算方法 但是大部分用户只用到其中一部分的功能 所以写了一个包括解方程，矩阵计算，排序功能的代码(As matlab provides some very useful method but most users only use part of the function it was a including solving equations, matrices, and sorting code)

说明：  用于生成不同频段的扫频信号，以供后期开发使用(create swept-frequency signal indifferent frequency channel )
