Create a contour plot that displays labels with one digit after the decimal point followed by the letter m. Specify a partially transparent fill color by setting the FaceAlpha property to 0.25. Get contourf(pe
This MATLAB function creates a filled contour plot containing the isolines of matrix Z, where Z contains height values on the x-y plane.
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...
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.
This MATLAB function creates a 3-D contour plot containing the isolines of matrix Z, where Z contains height values on the x-y plane.
Then, label the contour plot. Get [x,y,z] = peaks; [C,h] = contour(x,y,z); clabel(C,h) Label Specific Contour Levels Copy Code Copy Command Label only the contours with contour levels 2 or 6. Get [x,y,z] = peaks; [C,h] = contour(x,y,z); v = [2,6]; c...
