MATLAB

calculates the shortest path and distance between two nodes on a map

这是学习MATLAB很好的学习资料，是《MATLAB及在电子信息课程中的应用》一书的各章配套程序，很有帮助价值。(This is a very good learning materials to learn MATLAB is " MATLAB and in the course of electronic information" supporting the various chapters of the book program, useful values.)

采用解调分析方法，从信号中提取调制信息，分析其强度和频次就可以判断研究对象（诸如机械零件）损伤的程度和部位。(Using the demodulation method, the modulation information is extracted from the signal, the strength and frequency analysis can determine the study (such as mechanical parts) and location of the degree of damage.)

成像处理一般包括三个步骤：1、距离向脉冲压缩，对一个合成孔径内的每个回波脉冲均进行压缩；2、距离徙动矫正，把属于同一点目标的脉冲校正到等距离线上、3、方位向脉冲压缩。(Imaging process generally comprises three steps: a distance to the pulse compression of echo pulses each have an inner aperture compression 2, range migration correction, the pulses belonging to the same point in the correction target line equidistant , 3, azimuth compression to pulse.)

北工商Matlab课件，对初学者很有用；用Matlab解方程的程序源代码以及有限差分方程源代码，希望对学习Matlab的小朋友有帮助(North Business Matlab courseware, useful for beginners with Matlab equations for the source code and the finite difference equation is the code, hope to help children learn Matlab)

该程序是包含多种角点提取的方法，如harris-laplace、susan等(The program includes a variety of corner detection is the method, such as the harris-laplace, susan, etc.)
