matlab频谱分析 很有用(matlab spectrum analysis is useful)

说明：  几个VC++源代码，使用C-MEX文件来实现VC++与MATLAB的混合编程。(Several VC++ source code, the use of C-MEX file to achieve the VC++ and MATLAB programming mixed.)

基于二次型最优控制的起重机开环消摆方法的研究，这是很有创意的。(based on quadratic optimal control of the crane placed source open-loop method of research, this is very creative.)

Quadrotor Files Simulation

实现大点数的IFFT变换，先进行小点数IFFT变化，然后再进行过采样滤波，有频谱图及例子(Achieve great points IFFT transform, first have a small point IFFT change, and then over-sampling filter, a spectrum and examples)

fft的matlab编程实现，能够进行2的整数次幂的点数的fft运算，采用基2算法(fft in matlab programming, can be integral power of 2 points in the fft computation algorithm using radix-2)

说明：  噪声的加入小实验。用以实现 加入噪声的功能，从而发现，加入噪声的方法与表现。(MATLAB realase an input noise,and to make the photo become a nomal looking photo.)

张雪英编著的数字语音处理书中的程序，内容比较全面，程序质量有所保证，对于刚接触语音的新手有所帮助。。。。(ZHANG Xue-ying edited book digital voice processing program. . . For the fourth year voice newbie help. . . .)

功率谱估计及其MATLAB仿真.经典功率谱估计是将数据工作区外的未知数据假设为零,相当于数据加窗。经典功率谱估计方法分为:相关函数法(BT法)、周期图法以及两种改进的周期图估计法即平均周期图法和平滑平均周期图法,其中周期图法应用较多,具有代表性。(The power spectrum estimation and simulation of MATLAB. Classic power spectrum estimation is unknown data in the data outside the workspace is assumed to be zero, equivalent to the data window. Classic power spectrum estimation method is divided into: the correlation function method (BT Act), the periodogram and two improved cycle diagram estimation method the average periodogram and smoothed average periodogram, which the periodogram method used more often, on behalf of sex.)
