一、绘制函数图形 1 启动Graph软件，主界面如下。2 绘制出y=sin(x)的曲线，具体怎么会绘制参照下面引用的经验。二、绘制切线 1 先选中界面右侧已绘制函数，再执行菜单“函数|插入切线/法线”命令。弹出如下图所示的复选框。自己在其中设置想要的切线。2 我们设置的参数中画出了x=pi处的切线，其范围从x=0到x...
范数是一个标量,它是向量的长度或者模,$||x||$ 是 $x$ 在有限空间中坐标的连续函数。这里把 $x$ 简化成1维的,坐标之间的差值可以看作向量在空间中的距离,根据压缩映射的定义,可以导出: $$||F(x)-F(y)||{\leq}c||x-y||, 0\ {\leq}c<1$$ $$\frac{||F(x)-F(y)||}{||x-y||}{...

Line graphs consist of two axes: x-axis (horizontal) and y-axis (vertical). Each axis represents a different data type, and the points at which they intersect is (0,0). The x-axis is the independent axis because its values are not dependent on anything measured. The y-axis is the ...

Construct graph consists of (1) calculating the similarity between subsamples, (2) assigning weights, and (3) outputting the graph. The flow chart of construct graph are show in Fig. 3. Figure 3 Flow chart of construct graph. Full size image Similarity Let X = {X1, X2, X3…, ...
Representing a graph as a vector is a challenging task; ideally, the representation should be easily computable and conducive to effi- cient comparisons among graphs, tailored to the particular data and analytical task at hand. Unfortunately, a "one-size-fits-all" solution is unattainable, as di...

In this paper, we consider certain quantities that arise in the images of the so-called graph-tree indexes of graph groupoids. In text, the graph groupoids are induced by connected finite-directed graphs with more than one vertex. If a graph groupoid GG
