in this mfile i have wrote the principal component anlisys algorithm.

LDPC的译码算法，其中使用matlab和C的联合编程，C主要做了译码算法，并且有性能的仿真测试(LDPC decoding algorithm, including joint programming matlab and C, C major to do the decoding algorithm and performance simulation test)

把整个频率范围中的某段重点频区局部放大，获得比整个频率范围高的频率分辨率，从而观察频谱中的细微部分(The entire frequency range of the frequency of certain key areas enlarged to obtain the entire frequency range than the high frequency resolution, and thus observe the subtle part of the spectrum)

一组取值为+/-1的随机序列，每两个数据之间插入3个0，然后将序列通过一个设计好的根升余弦滤波器，并用周期图法和Welch法分别绘制信号的功率谱。再次通过根升余弦滤波器后用stem函数绘图。(A set of values ​ ​ is+ /-1 random sequence inserted between every two data 3 0, then the sequence through a root raised cosine filter designed, periodogram and Welch method to draw the signal powerspectrum. Stem function by root raised cosine filter with drawing again.)

RANSAC算法及其各种改进算法，以及仿真结果分析(RANSAC algorithm and its improved algorithm and analysis of simulation results)

指数Milstein 方法解非线性随机微分方程，考虑其收敛阶。(the convergence of exponential Milstein method to nonlinear stochastic differential equations, )

mathematical model of induction motor

用龙贝格法求定积分，此例的变量数为三，但整体思路是没错的。(With Romberg method for the definite integral, the number of variables in this case is three, but the overall idea is correct.)

MATLAB编程案例 小圆绕大圆内或外侧运动求小圆上一点的轨迹并画图(MATLAB Programming cases or outside the small circle around the great circle motion seeking a little on the small circle of track and drawing)

这个是学习MATLAB的书籍，适合基础较差的朋友(This is a learning MATLAB books, suitable for the basis of poorer Friend)
