在Matlab中，使用contour plot绘制等值线图是一种常见的方法。例如，可以绘制函数z = x * exp(-x^2 - y^2)的等值线图。首先，创建网格数据，这可以通过meshgrid函数实现：[x, y] = meshgrid(-2:.2:2, -1:.15:1);然后计算z值：z = x .* exp(-x.^2 - y.^2);接下来，使用gradie...
contour plot data.txt Hi. I have three columns of data. The first two columns are the x and y coordinates while the third one is the isoline column. Can anyone help me how to make a single contour plot in Matlab. I have attached the file here. Please help. Thanks. ...
Then display a filled contour plot of Z, letting MATLAB® choose the contour levels. Get Z = peaks; contourf(Z) Contours at Ten Levels Copy Code Copy Command Define Z as a function of two variables, X and Y. Then display contours at 10 levels of Z. Get x = linspace(-2*pi,2...
Zi — The height of the ithcontour line Ni — The number of vertices in the ithcontour line (xij, yij) — The coordinates of the vertices for the ithcontour line, where j ranges from 1 to Ni Contourobject. Use this object to set properties after displaying the contour plot. ...

This MATLAB function labels the current map contour plot by inserting rotated text into each contour line.
Display Contour Plot Under Mesh Plot Copy Code Copy Command Create three matrices of the same size. Then plot them as a mesh plot with a contour plot underneath. The mesh plot uses Z for both height and color. Get [X,Y] = meshgrid(-3:.125:3); Z = peaks(X,Y); meshc(X,Y,Z...
