以图像来说明建立空间特征基和小波变换的关系 设有一幅图像,从不同分辨率考察。 若我们离很远来看,可能会把每64个点看作一个点,若记此时构成的描述空间为V 若走进一些,把16个点看作一个点,记此时构成的描述空间为V1 若再走进一些,把4个点看作一个点,记此时构成的描述空间为V2 若再走进一些,把1个点看作一个点,记此时构成的描述空间为V3 则可知凡是Vi空间内可以描述的图像

定义在假设y=y(x),即第i步计算是精确的前提下,考 虑的截断误差R=y(x)-y称为局部截断误差鬥 local truncation error

Example 1. 1. The iterative rule po 1 and pk+1= 1.001pk for k=0, 1,..pro- duces a divergent sequence. The first 100 terms look as follows: P1=1.0170=(1.001010001.00100 p2=1011=(1001)(1.0000001 3=1012=(1001)(1.002011.00300 p100=1.0019(1.001)(1.104012)=1.105116

Theorem 3.7. (Elementary Transformations). The following opera- tions applied to a linear system yield an equivalent system: ()Interchange: The order of two equations can be changed. (2)Scaling: Multiplying an equation by a nonzero constant. (3)Replacement: An equation can be replaced by the sum of itself and a nonzero multiple of any other equation
