串级控制系统simulink仿真,对于新手来说很容易理解(Cascade control system simulink simulation, it is easy to understand for the novice)

FEM1D_SPECTRAL_NUMERIC is a MATLAB program which applies the spectral finite element method to solve the problem u = - pi^2 sin(x) over [-1,+1] with zero boundary conditions, using as basis elements the functions x^n*(x-1)*(x+1), and carrying out the integration numerically using MATLAB s quad() function. This function solves the problem u = - pi^2 * sin( pi * x ) for x in (-1,1), with boundary conditions u(-1) = u(1) = 0.

this code implement LTE scrambler and LTE descrambler used in the 4G mobiles release 8.parameters of these two blocks are flexible.

conjugate gradient algorithm for multivariable functions

说明：  该程序是在matlab中实现卡尔曼滤波的一个程序代码(The program is implemented in the matlab program code of a Kalman filter)

Knowledge of the process noise covariance matrix is essential for the application of Kalman filtering. However, it is usually a difficult task to obtain an explicit expression of for large time varying systems. This paper looks at an adaptive Kalman filter method for dynamic harmonic state estimation and harmonic injection tracking.(Knowledge of the process noise covariance matrix is essential for the application of Kalm an filtering.
