let's say there are 3 sections A, B and C, and each section carries same number of points. Those points are (x, y, z) coordinates, and each section is 2D matrix with same size. Then, I connect 1st point of A wit
This MATLAB function creates a mesh plot, which is a three-dimensional surface that has solid edge colors and no face colors.

It is also possible to draw multiple lines using a matrix. (4) 图形属性(Graphic properties) 三维线图与二维线图的属性设置相同,即在plot3函数中对线条的颜色、线型和标记类型等属性进行设置。 The attribute setting of the 3D line graph is the same as that of the 2D line graph, that is, the at...

矩阵(matrix)是一种特殊的向量,包含两个附加的属性:行数和列数。所以矩阵也是和向量一样,有模式(数据类型)的概念。(但反过来,向量却不能看作是只有一列或一行的矩阵。数组(array)是R里更一般的对象,矩阵是数组的一个特殊情形。数组可以是多维的。例如:一个三维数组可以包含行、列和层(layer),而一个矩阵只有...
This information is crucial for matrix assembly; P0 is a 3×1 array that contains the coordinates of a point w.r.t. which the element obj is star-shaped. VEMcomp needs this information later for the computation of local mass and stiffness matrices. However, the condition that each 2D ...
It offers similar behavior that you may be used to from MATLAB in terms of operation syntax. However, NumPy strongly recommends that you use the ndarray type because it is more flexible and because matrix will eventually be removed.In the rest of this section, you will get to know the ...
