水平集经典方法的matlab工具箱,可以省却大量精力。(level set by the classical method of Matlab toolbox, we can save a great deal of energy.)

数字下变频DDC的matlab原码，采用cordic算法(DDC The DDC matlab source code, you can refer to see)

This code computes the distance and azimuth an earthquake to a station. It is necessary to provide the latitude and longitude bothe for the earthquake and the station.

—The minimum variance distortionless response (MVDR) approach is very popular in array processing. It is also employed in spectral estimation where the Fourier matrix is used in the optimization process. First, we give a general form of the MVDR where any unitary matrix can be used to estimate the spectrum. Second and most importantly, we show how the MVDR method can be used to estimate the magnitude squared coherence function, which is very useful in so many applications but so few methods exist to estimate it. Simulations show that our algorithm givesmuchmore reliable results than the one based on the popular Welch’s method.

Joan Solà编写6自由度扩展卡尔曼滤波slam算法工具包，解决视觉和机器人定位SLAM的一些列算法matlab工具包，对机器人定位和地图创建以及基于视觉的定位有很大帮助(This toolbox performs 6DOF SLAM using the classical EKF implementation. It is conceived as an "active-search" SLAM. It is provided for free under the GPL license (please read the file COPYING and make sure you agree in the terms and conditions before using it). Users might consider citing in their scientific communications one of the papers of the authors (SOLA-ETAL-IROS-05a, SOLA-ETAL-TRO-08, SOLA-ETAL-IROS-09) appearing on the References section in the documentation, and also acknowledging the use of this toolbox.)

This program communicates with serial port and send the SMS to the specified mobile number. It requires GSM kit to be connected with serial port.
