This MATLAB function creates a filled contour plot containing the isolines of matrix Z, where Z contains height values on the x-y plane.
contourf(Z) creates a filled contour plot containing the isolines of matrix Z, where Z contains height values on the x-y plane. MATLAB® automatically selects the contour lines to display. The column and row indices of Z are the x and y coordinates in the plane, respectively. example co...

This MATLAB function creates a filled contour plot of the regular data grid Z that is spatially referenced by the geographic raster reference object R.
contour3(Z) creates a 3-D contour plot containing the isolines of matrix Z, where Z contains height values on the x-y plane. MATLAB® automatically selects the contour lines to display. The column and row indices of Z are the x and y coordinates in the plane, respectively. example co...
contour(X,Y,Z,'r--'); % 使用红色虚线绘制等高线 填充等高线之间的区域 使用contourf 函数可以填充等高线之间的区域: contourf(X,Y,Z); colorbar; % 通常与 colorbar 一起使用来显示颜色映射 手动指定等高线级别 你可以手动指定等高线的级别: levels = [-5:-1 0 1:5]; % 定义等高线级别 contour(X...
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...
