机器人路径规划程序，matlab编程。具有参考性。(Robot path planning procedures, matlab programming.)

在东北天坐标系下对惯导进行解算的程序，可以结合之前上传的生成原始数据的源代码进行验证，当不添加噪声时，此程序解算的结果与真实轨迹几乎一致（不完全一致是因为积分采用近似算法）(INS calculation in ENU coordinate frame)

The program uses a simple algorithm to calculate the deflection at each point of a cantilever beam subjected to arbitrary loading distribution, the program also calculates and plots the bending moment and shear force in the beam.

盲源分离的自适应在线学习方法，采用最大熵，四个源信号，四个混合信号和自然梯度方法(Adaptive online learning method for blind source separation using the maximum entropy, four source signals, four mixed-signal, and the natural gradient method)

小波变换的重建，通过matlab内的小波包函数实现(The reconstruction of the wavelet transform, wavelet packet is realized by Matlab function)
