一种适用于多自由度的自然激励技术，可以实现从随机响应信号中提取自由振动信号。(A multi-degree of freedom for the natural excitation technique, can extract from the random response signal free vibration signals.)

三角剖分matlab实现的三角剖分，形成网格模型(Triangulation matlab achieve triangulation, to form a grid model)

代码详细实现了信号和图像的模极大值重构的 S.mallat 交替投影算法，该方法具有收敛速度快、精度高的特点。(The code depicts the modulus maxima recovery of signal and image based on the S.Mallat s alternate projection algorithm. The algorithm has fast convergence and high accuracy. )

模糊PID控制算法,对模糊控制与pid的结合的学习有帮助(mo hu pid)

检测电机转速通过pid算法对电机PWM占空比调节使电机达到预定转速(The motor speed is detected, and the duty cycle of the motor PWM is adjusted by the PID algorithm, so that the motor reaches the desired speed)

This is not my work but a function I use often. It is much faster than the conv2 function in matlab
