考虑以下问题：给定 R(mxn) 中的矩阵 A，R(m) 中的向量 b 且 e>0，计算满足 norm(Ax-b)<=e 的向量 x，如果存在，则 x在所有这些向量中具有最少数量的非零条目。

一本非常经典的作品，数学、工程特别是小波分析与机器学习领域的人非常有必要一看。这是我在网上辛辛苦苦前后找了几年才找到的宝贝。

Tensor Decompositions and Applications 的专业文章 对了解tensor很有用

This series is published jointly by the Mathematical Optimization Society and the Society for Industrial and Applied Mathematics. It includes research monographs, books on applications, textbooks at all levels, and tutorials. Besides being of high scientific quality, books in the series must advance the understanding and practice of optimization. They must also be written clearly and at an appropriate level for the intended audience.

The finite element method is the most popular general purpose technique for computing accurate solutions to partial differential equations (PDEs). Since PDEs form the basis for many mathematical models in the physical sciences and, increasingly, in other fields as well, it would be difficult to overstate the importance of the finite element method.
