单摆运动过程的建模和仿真，忽略空气阻力因素(Pendulum movement of the modeling and simulation process, ignore the air resistance factor)

Modeling crack growth in a traditional finite element framework is a challenging engineering task. Originally the finite element framework was modified to accommodate the discontinuities that are caused by phenomena such as cracks, inclusions and voids. The finite element framework is not well suited for modeling crack growth because the domain of interest is defined by the mesh. At each increment of crack growth, at least the domain surrounding the crack tip must be remeshed such that the updated crack geometry is accurately represented.

步进频信号处理模型，从信号产生到信号处理过程，到输出(step frequency)

说明：  Fm 的调制和解调 可以在matlab直接运行，包含模块文件(Fm modulation and demodulation can be run in matlab directly, including the module file)

Backpropagation, an abbreviation for backward propagation of errors , is a common method of training artificial neural networks used in conjunction with an optimization method such as gradient descent. The method calculates the gradient of a loss function with respects to all the weights in the network.
