改程序可以进行奇异值分解。是一种压缩后的奇异值分解。也可以进行广义奇异值分解。DSVD Damped SVD and GSVD regularization.(Program can change the singular value decomposition. Is a compressed singular value decomposition. Can also be generalized singular value decomposition. DSVD Damped SVD and GSVD regularization.)

在发送总功率限制下的，多用户MIMO块对角化（BD）预编码算法的和速率仿真。功率分配采用注水算法。(Send the total power limit, the multi-user MIMO block diagonalization (BD) precoding algorithm simulation and rate. Power allocation is water-filling algorithm.)

小波分析由于具有同时分析信号时域和频域的特性，所以使用小波分析技术对检测的信号进行变换，然后对具有故障特性的信号进行重构，最后通过希尔伯特变换进行解调和细化频谱分析，从而轴承中的故障信息成分就可以检测出来，以判断轴承发成故障的部位。(Wavelet analysis has the characteristics of both time and frequency domain, so the wavelet analysis technique is used to transform the signal, then the signal is reconstructed. Finally, the fault information components of the bearing can be detected by Hilbert transform.)

说明：  网络函数逼近实例1.首先定义正弦函数，采样率为20Hz，频率为1Hz 2.生成BP网络。用newff函数生成前向型BP网络，设定隐层中神经元数目为10 3.对生成的网络进行仿真并做图显示。 4.训练。对网络进行训练，设定训练误差目标为 1e-5，最大迭代次数为300 5.再次对生成的网络进行仿真并做图显示。(Network function approximation example)
