Matlab fdtd （时域有限差分）一维，二维，三维集合(Matlab fdtd (FDTD) one-dimensional, two-dimensional, three-dimensional collection)

this is the model of an inverted pendulum, whereas the drivetrain is modeled as PT1 system. some of the code desctiption may be in german. to run just open the m-file and click :run

压缩感知程序源码，Blind compressed sensing (BCS)不需要在采样和恢复阶段预先知道稀疏基。源码对于研究压缩感知前沿具有很好的借鉴意义。(The fundamental principle underlying compressed sensing is that a signal, which is sparse under some basis representation, can be recovered from a small number of linear measurements. However, prior knowledge of the sparsity basis is essential for the recovery process. Blind compressed sensing (BCS) avoids the need to know the sparsity basis in both the sampling and the recovery process. That is, BCS aims at recovering an ensemble of vectors, all sparse under the same unknown basis, given small number of linear measurements of these vectors. )
