用root—music方法计算正弦信号的频率估计(root-music )

shenasai system control modern

把已知的时域信号进行傅里叶变换在频域上显示。(If you are running a lot of time based simulations, often you will want to see the frequency response. Here is a function that may help.)

利用MATLAB开发软件进行编程，实现了数字IIR低通滤波器的功能，程序直接可以运行！(Use MATLAB to develop software for programming, implementation of digital IIR low-pass filter function, the program can run directly!)

利用快速傅里叶变换求两幅图像的卷积，matlab源码(Fast Fourier transform using the convolution of two images, matlab source)

图像加密隐藏的一个用MATLAB编写的好程序。(Hidden image encryption using MATLAB write a good program.)

matlab编写的基于特征点的图像配准的代码，希望对大家有用(matlab feature point-based image registration code, written in the hope that useful)

说明：  在阵列信号处理中,可以对信号的来波方向进行估计,并计算其估计误差!(In array signal processing, the signal can be estimated to wave direction, and calculate the estimation error!)

carlight1中是一个用C编的程序，用于计算每条光线在测试屏上的坐标(carlight 1 is a C series of the program, each ray is used to calculate the coordinates on the screen in the test)
