butterworth lowpass filter used for finding speech signal.

有关于梳状滤波器的设计源码，大家可以参考，不错的(Comb filter on the design of source code, we can refer to, well)

interop between C# and matlab

基于matlab实现的合成孔径雷达SAR的CS算法的模拟仿真(Based on simulation matlab implementation of synthetic aperture radar SAR of CS algorithm)

定义锁相环的工作模式：单载波为“1”、BPSK调制为“2”、QPSK调制为“3”(The definition of phase-locked loop mode of operation: single-carrier for the " 1" , BPSK modulation for the " 2" , QPSK modulation for the " 3" )

说明：  mmse与snr的算法仿真，最小均方误差和最大信噪比，获得自适应算法的最优权，实现抗干扰(mmse snr algorithm and simulation, the minimum mean square error and maximum signal to noise ratio, the right of access to optimal adaptive algorithm to achieve anti-jamming)

图像的几何矫算法及其用MATLAB实现的代码，内容全面，包含图片(The geometry of the image by algorithm and MATLAB code, comprehensive, including pictures )

基于非线性扩展卡尔曼滤波的Matlab程序(The extended Kalman filter can not only estimate states of nonlinear dynamic systems from noisy measurements but also can be used to estimate parameters of a nonlinear system. A direct application of parameter estimation is to train artificial neural networks. This function and an embeded example shows a way how this can be done.)

本代码是基于MATLAB的模糊pid的仿真程序，经测试可以运行。(The code is based on the MATLAB simulation of the fuzzy pid process can run through the test.)

可以解出一个线性矩阵不等式中的未知矩阵。(Can solve a linear matrix inequality in the unknown matrix.)
