The CoinUtils project is a collection of open-source utilities developed and used by a variety of other projects in the COIN-OR repository. The project includes classes for storing and manipulating sparse matrices and vectors, performing matrix factorization, parsing input files in standard formats, ...
论文 A Rate Adaptive Channel Estimation Approach
In this paper, we consider the channel estimation
problem in Millimeter wave (mmWave) wireless systems with
large antenna arrays. By exploiting the inherent sparse nature of
the mmWave channel, we develop a novel rate-adaptive channel
estimation (RACE) algorithm, which can adaptively adjust the
numb ...
3G开发 The MDP toolbox proposes functions related to the resolution of discrete-time Markov Decision Proces
The MDP toolbox proposes functions related to the resolution of discrete-time Markov Decision Process : finite horizon, value iteration, policy iteration, linear programming algorithms with some variants.
The functions (m-functions) were developped with MATLAB v6.0 (one of the functions requires th ...

Abstract - A &#64258 exible multiscale and directional representation for images is
proposed. The scheme combines directional &#64257 lter banks with the
Laplacian pyramid to provides a sparse representation for two-
dimensional piecewise smooth signals resembling images. The
underlying expansion is ...
数值算法/人工智能 改进平方根法求解对称正定线性方程组
改进平方根法求解对称正定线性方程组，用matlab编写，可以在一定程度上提高求解效率。其中MRoot_squaring.m为原做法，sparse_cmp.m为二维等带宽存储，Moot_zonal.m为二维等带宽存储的平方根法求解
数学计算 The inverse of the gradient function. I ve provided versions that work on 1-d vectors, or 2-d or 3-d
The inverse of the gradient function. I ve provided versions that work on 1-d vectors, or 2-d or 3-d arrays. In the 1-d case I offer 5 different methods, from cumtrapz, and an integrated cubic spline, plus several finite difference methods.
In higher dimensions, only a finite difference/linear alge ...
传感与控制 改进SRC算法在人脸识别中的应用
稀疏表示分类算法（Sparse Representation-based Classification，SRC）在人脸数据库上有很高的识别性能。然而，对于姿态变化，SRC的识别效果并不理想。针对SRC算法不能解决测试样本与训练样本存在偏移误差的问题，本文提出了基于SRC的改进算法。该算法将每一类的训练样本单独作为训练字典，利用迭代校正和基于金字塔分层机 ...
