q717是验证时域采样与频域采样的对偶性，q718是快速卷积运算(q717 is to verify the time domain sampling and frequency-domain sampling of the duality, q718 is fast convolution)

说明：  故障诊断的数据，仿真软件试验多次做出来的，有参考价值(Fault diagnosis data, simulation software, testing out several times to do, there is reference value)

A Hopfield network is a form of recurrent artificial neural network invented by John Hopfield in 1982. Hopfield nets serve as content-addressable memory systems with binary threshold nodes. They are guaranteed to converge to a local minimum, but convergence to a false pattern (wrong local minimum) rather than the stored pattern (expected local minimum) can occur. Hopfield networks also provide a model for understanding human memory.

在MATLAB上实现的MSK调制与解调程序。(Implemented on the MATLAB MSK modulation and demodulation process.)

本代码实现基本的GMSK调制解调的功能，经过调试可用(The code to achieve basic GMSK modulation and demodulation functions available through debugging)

nearestSPD works on any matrix, and it is reasonably fast. As a test, randn generates a matrix that is not symmetric nor is it at all positive definite in general.
