The code for Surface is surf(), surf(X,Y,Z) creates a three-dimensional surface plot, which is a three-dimensional surface that has solid edge colors and solid face colors. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y. The...
Matlab中预设了数十种不同的colormap颜色图,如图:A colormap is a matrix of values that define the colors for graphics objects such as surface, image, and patch objects. MATLAB draws the objects by mapping data values to colors in the colormap. Dozens of different colormap color maps are prese...
matlab，其名称是由MATrix和 LABoratory（矩阵实验室）两个单词的前三个字母所合成。在1978年，Malab就面世了。这个程序获得了很大的成功，受到了学生的广泛欢迎。在以后的几年里，Matlab在多所大学里作为教学辅助软件使用，并作为面向大众的免费软件广为流传。方法/步骤 1 第一步小伙伴们打开自己电脑桌面上找到matlab...
Plot (X1, Y1,..., Xn, Yn) plots multiple pairs of x and y coordinates on the same set of axes. This syntax is an alternative to specifying the coordinates as a matrix. 使用plot函数绘图时,先要取得x、 y坐标,然后再绘制曲线,x往往采取等间隔采样。在实际应用中,函数随着自变量的变化趋势未知...
well... i tried to use both answers and the realiza same thing: figure divided in color by the numbers in matrix. instead i want to know how to have a picture(jpg for intend) that is my matrix if A=[1 2 3;4 5 6;7 8 9]; i want to realize a way to picture a matrix with...
1 plot（）函数是用来绘制平面坐标图形的，在command window中输入x=0:pi/10:2*pi;y=sin(x);plot(x,y) 接着出现图形窗口，可以看到我们的sin图像，如简介图示 2 生成的图像是采用的默认设置，我们也可以自己修改设置，再plot中输入设置的参数，比如我们将线条颜色改为红色在command window中输入plot(x,y,&#...

方法/步骤 1 为了验证，可以通过plot（x，y）和plot（x'，y'）来实现。下面是程序代码 2 t=[0,120,240,0]*pi/180;%变换成弧度xxx=[];yyy=[];for i=0:5:360 tt=i*pi/180; xxx=[xxx;cos(tt+t)];yyy=[yyy;sin(tt+t)];endplot(xxx,yyy,'r'),axis('...
