presentation of MATLAB

TRAINDIFFEVOL(NET,Pd,Tl,Ai,Q,TS,VV) takes these inputs, NET - Neural network. Pd - Delayed input vectors. Tl - Layer target vectors. Ai - Initial input delay conditions. Q - Batch size. TS - Time steps. VV - Either empty matrix [] or structure of validation vectors. and returns, NET - Trained network. TR - Training record of various values over each epoch: TR.epoch - Epoch number. TR.perf - Training performance. TR.vperf - Validation performance. TR.tperf - Test performance. TR.mu - Adaptive mu value.

包含特征值与特征向量的提取、训练样本以及最后的识别，LDPC码的完整的编译码，多抽样率信号处理，包括四元数的各种计算,可以提取一幅图中想要的目标，采用累计贡献率的方法。

无线多载波_MIMO_OFDM_系统的理论和关键技术研究，优秀博士论文，做MIMO和OFDM很好的参考(_MIMO_OFDM_ Wireless multi-carrier system theory and key technology research, outstanding doctoral dissertation, MIMO and OFDM make a good reference)

说明：  ldpc码的基于联合校验—变量处理修正译码算法基础上的改进(the improvement of LDPC code decoding algorithm )

一个很不错的用时域有限差分法解决二维直角坐标系下正方格子的matlab程序(a very good use of the finite difference time domain method to solve two-dimensional Cartesian coordinate system is the square lattice procedures Matlab)

可直接计算得到多重分形谱,有借鉴意义哦，可以实现模式识别领域的数据的分类及回归，采用的是脉冲对消法，正确率可以达到98％，基于欧几里得距离的聚类分析。
