SparseArray

梯度下降法的matlab版本实例,带收敛轨迹图。(the steepest descent algorithm with matlab )

matalab程序好用便捷，关于宏观经济，有增长，有波动研究。(matalab program easy to use and convenient, on the macro economy, there is growth, there are fluctuations in research.)

Analyze performance of 3D FDFD algorithm for large systems.

水下无人航行器（AUV）simulink仿真工具箱,安装后即可用里面给出的各种AUV模型进行仿真，是挪威科技大学的学生做的，很不错。(Unmanned underwater vehicle (AUV) simulink simulation toolbox, which can be used after installation of various AUV model given simulation, the Norwegian University of Technology, students do very well.)

给原始信号加入噪声，然后让信号经过卡尔曼滤波器，比较原始信号、加噪声后信号及通过卡尔曼滤波器的信号的图像。(Adding noise to the original signal, and then let the signal through the Kalman filter, compare the original signal, the signal plus noise and the signal through the Kalman filter images.)

动态SVM算法，可实现模型的在线实时更新，里面的数据需要根据自己的实际数据改变，为一多输入单输出的拟合预测模型。(Dynamic SVM algorithm can achieve real-time updates online model, the data inside the data according to their actual needs change, fitting prediction model is a multi-input single-output.)

说明：  MATLAB 拥有大量的常用数学函数、工具箱，基本包括了现今数学、物理及工程应用领域的 常用函数，如能熟练掌握，无论在编程时间或程序量上，都远远低于Fortran、C 等高级语言，尤其在 处理矩阵和向量计算方面更具有无可比拟的优势。 我们在数学建模竞赛中，由于只有短短的三到四天，而论文的评判不仅注重计算的结果更注重模型 的创造性，比赛中把大量的时间花费在编写和调试程序上只会喧宾夺主，这是不值得的，这时使用 MATLAB 可以很大程度上的方便计算、节省时间，使我们将精力更多的放在模型的完善上，所以是较 为理想的。 这里我们仅举了一些运用 MATLAB 的例子，这些都是在数学建 模中时常遇到的问题，希望能抛砖引玉，帮助同学们在数学建模中方便、快捷的使用MATLAB，并善用这一工具。(mathematical modeling question Matlab example)

这是较好的Matlab源代码，希望此代码能对大家有所帮助。(This is a better Matlab source code, I hope this code can be helpful to everyone.)
