mathews数值分析书的源代码，用matlab编写，可以对照书本学习。(mathews numerical analysis of the book' s source code, using matlab, you can control book-learning.)

matlab的命令，很全很给力，大家可以作为字典用(Matlab command very wide to the force, we can use as a dictionary )

ATLAB an integral part of their study of Communication Systems topics and concepts. The books in this new series are designed to promote students problem solving and critical thinking skills through the use of MATLAB as a "virtual laboratory." A 3.5" disk containing supporting MATLAB data

Sample Code which helps to understand how to use LocationManager.

用LU分解法解线性方程组Ax=b。用牛顿法求非线性方程f(x)=0(With the LU decomposition method of solving linear equations Ax = b. Using Newton s method for nonlinear equation f (x) = 0 )

无约束问题最优化方法的核心问题是选择搜索方向。 以正定二次函数为例，来观察两个方向关于矩阵Ａ共轭的几何意义(Unconstrained optimization problems are most core issue is to choose the search direction. In definite quadratic function, for example, to observe both directions on the matrix A conjugate geometric meaning)

The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform. For Haar transform, the transformation matrix H contains the Haar basis functions hk(x). They are defined on a continuous, closed interval, x -[0, 1] for k = 0,1,2 ...,N -1 where N = 2n.( The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform.
