MATLAB 有约束信赖域算法，以四元多项式为算例 适用于学习最优化算法的数学专业学生以及其他数值分析课程的同学， 程序清晰，对MATLAB的学习也有很大的帮助，同时程序还有一些不足，读者自己须根据实际问题更正。(MATLAB constrained trust region algorithm to quaternion polynomial example for the application of optimization algorithms in the learning of mathematics students, as well as other courses in numerical analysis of the students, the program clearly and learning to MATLAB is also a great help, but the procedure also There are a number of shortcomings, the reader himself to be corrected in accordance with the actual problem.)

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!)

特征提取的matlab代码，，，，非常好哦啊～～～(Feature extraction matlab code,,,, very Ay ah ~ ~ ~)

小波去噪的matlab程序。有三种阈值选择方法：标准的，强制的，自己设置的。(Wavelet denoising matlab program. There are three kinds of threshold selection method: standard, mandatory, set up their own.)

数字识别，通过matlab对0-9几各简单的数字进行识别(Digital identification)

SVM using matlab processing

说明：  随机共振检测弱信号，a_b_f是主程序，sr是rk4算法，模拟双势阱中粒子运动(Stochastic resonance detection of weak signals, a_b_f is the main program, sr is rk4 algorithms, simulated double potential well of particle motion)
