捷联惯导四元数误差模型，采用ukf作为滤波方法。(nonlinear alignment method for sins)

主动频率偏移法的改进,可以作为参考，只是需要一定的文献才能看懂(this s a typical method to solve the problem about the isolated land)

采用BFGS变尺度算法求解无约束优化问题的matlab程序代码(BFGS variable scaling algorithm for solving constrained optimization problems matlab code)

The aim of this short workshop is to demonstrate the effectiveness of the JPEG encoding/decoding process using test data and test images. As explained in the lectures the major elements of the JPEG encoding process are the DCT, the non-uniform Quantisation matrix and variable run-length encoding. Building an emulator of the JPEG encoding and decoding algorithm may appear a daunting task, but Matlab is well suited to such coding.

这是我在网上找到的，里面比较详细的介绍了QPSK的仿真。(This is what I found on the Internet, where a more detailed introduction to the QPSK simulation.)

matlab中边频的示例程序，操作简单，可直接复制，便于调用。(side frequency in matlab sample program, simple operation, can be directly copied, easy call.)

解helmholtz方程的matlab程序，这个程序是解线性方程的。(Solutions helmholtz equations matlab program that is the solution of linear equations.)

说明：  偏微分方程的特殊解法，非常经典，欢迎下载(Special solution of partial differential equations, very classic, please download)

在Matlab下，实现jacob滤波算法，非常实用(In Matlab, to achieve jacob filtering algorithm is very practical)
