kalman filter is described in this code and implemented

说明：  最小化l1范数的Matlab代码。求解模型为： min lambda*|x|_1+||A*x-y||_2。其中，|x|_1表示x的1-范数，||*||_2表示2-范数。该模型在稀疏成分分析、压缩传感器等领域有广泛的用途。( l1-Regularized Least Squares Problem Solver l1_ls solves problems of the following form: minimize ||A*x-y||^2+ lambda*sum|x_i|, where A and y are problem data and x is variable (described below). )

MATLAB课件，该课件是中文的，较容易学习，对于不熟悉英语的人有一定的好处。(MATLAB courseware, the courseware is Chinese, and more easy to learn, for people who are not familiar with English, have a certain advantage.)
