Toolbox for Numerical Computing with MATLAB （by Cleve Moler).
Numerical Computing with MATLAB （by Cleve Moler) is a textbook for an introductory course
in numerical methods, Matlab, and technical computing. The emphasis is on in-
formed use of mathematical software. We want you learn enough about the mathe-
matical functions in Matlab that you will be able to use them correctly, appreciate
their limitations, and modify them when necessary to suit your own needs. The
topics include
* introduction to Matlab,
* linear equations,
* interpolation,
* zero and roots,
* least squares,
* quadrature,
* ordinary di?erential equations,
* random numbers,
* Fourier analysis,
* eigenvalues and singular values,
* partial differential equations.(Toolbox for Numerical Computing with MATLAB (by Cleve Moler).

emd_online
将文件扩展名改成“.m”就可以直接放在工具箱里用了
计算经验模态分解( EMD_ONLINE (On Line Empirical Mode Decomposition) computes on-line EMD
IMPORTANT: EMD_ONLINE does not truly apply EMD on-line but it does AS IF.
It is rather a demonstration that EMD can be applied on-line.)

LTE (Long Term Evolution) and LTE-Advanced have been developed to respond to the
requirements of this era and to realize the goal of achieving global broadband mobile communications.
The goals and objectives of this evolved system include higher radio access data
rates, improved system capacity and coverage, flexible bandwidth operations, significantly
improved spectral efficiency, low latency, reduced operating costs, multi-antenna support, and
seamless integration with the Internet and existing mobile communication systems.
The LTE physical layer includes transmissions in uplink and downlink. The uplink transmissions are governed by PUSCH. The throughput performance of PUSCH is analyzed here
