MATLAB

在网上下载到的各种降维方法的MATLAB程序，希望对大家能有所帮助(Downloaded to a variety of methods of dimensionality reduction MATLAB procedures, in the hope that we can help)

时频分析工具箱，希望对大家有用，如果需要文件的说明，请留下联系方式(Time-frequency analysis toolbox, we hope to be useful, if you need the file, please leave a contact)

这次上传的绝对是好东西，数值优化，关键是对不同函数进行运算。这次将无约束测试问题上传，可作为论文数值计算使用。注：本人本科毕业论文做的是无约束优化，研究生做的是结构方程(LISREL)、数值优化、蚁群算法，可以进行交流，联系QQ272958823(Test function for optimation!)

均匀平面波在无损耗媒质中传播时，平面波的电场与磁场的振幅之比等于媒质的本征阻抗，在理想介质中，阻抗为一正实数。因为电场、磁场方向始终不变，根据它们的值，利用MATLAB提供的实现动态轨迹.(Uniform plane wave propagation in the lossless medium, the plane wave of electric and magnetic fields is equal to the ratio of the amplitude of the intrinsic impedance of medium, in an ideal medium, impedance is a positive real number. Because the electric field, magnetic field direction remains unchanged, according to their values, provided by MATLAB dynamic trajectory.)

一个MATLAB工具箱，可以进行快速而可靠的听觉阈值的计算！目前很少有类似的方法。(A MATLAB toolbox for rapid and reliable auditory threshold estimation)

用周期循环检测算法检测： 首先运行a.m程序，通过此程序运算得出循环频率a值； 再运行zhouqi.m程序，对a值进行确定，通过周期循环算法对信号进行检测； (With cycle detection algorithm to detect: First run am program, through this program computing a value obtained cyclic frequency zhouqi.m then run the program, for a value determined by the cycle algorithm of signal detection )

These are MATLAB codes for implementing Chebyshev-Type 1 Bandpass and Bandstop filters.

说明：  有关时频分析的matlab的程序 希望对大家有所帮助(the time-frequency analysis of the procedures Matlab we hope to help)
