MATLAB常用三维绘图
本帖最后由 稻香 于 2022-1-14 17:26 编辑在实际的应用中，我们常常需要将最后的数值结构表示成三维图形。在使用MATLAB绘制三维图时，与二维图形的绘制有许多相似之处，其中属性的设置是完全相同的。常见的三维图形包括三维曲线、三维网格图和三维曲面图。
01plot3（）函数Plot3 (x,y,z)，其中x,y,z是三个相同长度的向量；plot3(X,Y,Z)，其中X,Y,Z是三个相同大小的矩阵；plot3(X,Y,Z,s)，其中s可对线条的属性进行设置输入指令：Plot3 (x,y,z), where x,y, and z are three vectors of the same length;Plot3 (X,Y,Z), where X,Y, and Z are three matrices of the same size;Plot3 (X,Y,Z,s), where s can set the attributes of the lineInput instruction:02peaks()函数=peaks(n):该函数产生3个矩阵x、y和z,大小都为n*n。
输入指令：= Peaks (n): This function generates three matrices x, y, and z, each of size n*n.
Input instruction:
03mesh函数mesh函数用于制作三维网格图，函数格式为mesh(x,y,z, c),x和y控制x轴和y轴，矩阵z为z轴数据，图形的颜色采用参数c设置。The Mesh function is used to make 3D mesh graphs. The function format is Mesh (X, Y, Z, C). X and Y control X and Y axes.04surf（）函数Surf（）函数用于绘制彩色的三维曲面图。在MATLAB中采用函数surfc()绘制带有等高线的三维曲面图，通过函数surfl()添加三维曲面的光照效果,调用方式和surf( )相同。The Surf () function is used to draw color 3D curved surface diagrams. In Matlab, the function surfc() is used to draw a 3D surface graph with contour lines, and the illumination effect of 3D surface is added through the function surfl(), which is called in the same way as surf().在MATLAB中采用函数surfc()绘制带有等高线的三维曲面图，通过函数surfl()添加三维曲面的光照效果,调用方式和surf( )相同。Surfc()函数效果图：In Matlab, the function surfc() is used to draw a 3D surface graph with contour lines, and the illumination effect of 3D surface is added through the function surfl(), which is called in the same way as surf().Surfc() function renderings:05stem3（）函数在MATLAB中,三维柱状图、饼状图、火柴杆图等函数的调用格式和二维图的函数调用格式都非常相似，以火柴杆图为例：In Matlab, the call format of functions such as 3D histogram, pie graph and matchstick graph is very similar to that of 2D graph. Take matchstick graph for example:
