MATLAB simulation of group velocity dispersion in an optical fiber

说明：  基于HSM（harmonic-to-subharmonic）的基音提取算法。本算法通过对HSM建模，消除了基音提取过程中基音减半或增倍的现象，大大提高了准确性能。(Based on HSM (harmonic-to-subharmonic) of the pitch extraction algorithm. HSM model by the algorithm, the extraction process to eliminate the pitch halving or pitch doubling phenomenon, greatly improving the accuracy of performance.)

一本英文版的利用matlab进行光学扫描全息处理的电子书籍(An English version of the optical scanning holographic processing using matlab electronic books)

1. 识别同一个乐器弹奏出的不同音符（基波分析） 2. 识别弹奏出同一个音符的不同乐器（谐波分析）(1. identify the different notes played by the same instrument (fundamental analysis). 2. identify different musical instruments playing the same note (harmonic analysis).)

说明：  粒子滤波代码，是用MATLAB实现的,可以参考(Particle filter code is the use of MATLAB to achieve, can refer to)

matlab生成dll方法的心得体会,十分适合初学者，值得借鉴(as above,the way to create dll by matlab)

OFDM的QPSK调制与解调,有说明，有需要的朋友可以看看(OFDM QPSK modulation and demodulation, a note, a friend in need can look)

Field Ⅱ超声成像代码，可以进行单个孔径成像和合成孔径成像、加权和不加权仿真。(The calculation of point spread functions is done by placing a point in front of the transducer and then sweeping the beam over the point. This gives the point spread function of the imaging system. Field II can make this calculation for a number of points simultaneously and thereby reveal the dynamic focusing properties of the imaging system. A point phantom has been made for this purpose. It consists of a number of point targets placed with a distance of 5 mm starting at 15 mm from the transducer surface)

This is the matlab code for image segmentation where image segmentation is done through feature points
