matlab基本知识教程以及在现实中的一些应用(basic knowledge of matlab tutorials and some applications in the real world)

说明：  Welch法功率谱密度 Psd自功率谱 是用改进的平均周期图法来求随机信号的自功率谱估计 采用信号重叠分段，加窗函数和fft算法等计算一个信号的自功率谱估计（PSD）

步进频率连续波信号压缩仿真，详细展示其信号模型特点。(Simulate the compression of stepped-frequency continuous waves, showing the details of the signal model.)

this is the simulation designed to know the switching time of the svpwm and the simulink model of the 6-pulse invetre and induction model with the krause d-q transformation is simulated .......

matlab经典算法的程序之插值与拟合，多项式的插值与拟合等程序(classical algorithm matlab interpolation and fitting procedures, such as polynomial interpolation and fitting procedures)

matlab基础程序——代数方程解法，适合初学者(matlab-based program- calculus and differential equations, suitable for beginners)
