matlab各种周期信号的频谱分析matlab各种周期信号的频谱分析。(matlab various periodic signal range of the spectrum analyzer matlab cycle spectrum analysis of signals.)

说明：  主要是介绍卡尔曼滤波器的原理，并形象地说明了实现过程，最后用matlab实现了这一原理。(Mainly to introduce the principle of Kalman filter, and vividly illustrates the realization of the process, and finally use matlab to achieve this principle.)

说明：  为MATLAB中的图形增加标签，从而可以有效地表示图形意义，防止读不懂图的情况( BWLABEL supports 2-D inputs only, whereas BWLABELN support any input dimension. In some cases you might prefer to use BWLABELN even for 2-D problems because it can be faster. If you have a 2-D input whose objects are relatively "thick" in the vertical direction, BWLABEL will probably be faster otherwise BWLABELN will probably be faster.)

一个用matlab编写的用公式算法解决微波网络中的双支节匹配的问题(An equation using matlab algorithm to solve microwave network using the double-stub matching problem)

一个很好的基于matlab的pls工具箱，可以进多线性数据的的主成分分析，偏最小二乘回归等。(A good toolbox based on matlab' s pls, can enter the data more linear principal component analysis, partial least squares regression.)

方程求根的是抛物线法则，写的不好。仅供参考(Roots of the equation is parabolic law, badly written. Reference)
