contour(Z) creates a 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 contour(X...
I am wondering if it is possible to label the contours of a MATLAB contour plot with a set of user-defined strings? I am currently using the following code snipper to produce a labelled contour plot: %Create Data X = 0.01:0.01:0.10 Y = 0.01:0.01:0.10 Z = repmat(X.^2,len...
不知道是不是需要符合要求，看个例子吧 [x,y] = meshgrid(-2:.2:2,-1:.15:1);z = x .* exp(-x.^2 - y.^2); [px,py] = gradient(z,.2,.15);contour(x,y,z), hold on quiver(x,y,px,py), hold off, axis image ...

I have a problem getting matlab to plot the velocity contour which I can see in CFX POST. I tried exporting x,y,z and the velocity vector (.csv) at a giving plane but I can't seem to get the same contour plot in matlab (when using the "contour" command). Does anyone know how ...

I have a 3D data in which the x and y are piece-wise constant and z is constant in the interval of x and y. I would like to plot them with Matlab contourf function. The problem is that for an interval x,y the value z is interpolated. For example for x between x1 and x2 and...
第一,网格数据,往往是两个一维向量,然后可以通过meshgrid()函数构建MATLAB需要的标准的网格数据的格式。只是构建的时候需要注意一些方面。文档有提到。 SURF(x,y,Z) and SURF(x,y,Z,C), with twovector arguments replacingthe first two matrix arguments, must have length(x) =n and length(y) = m where...
This MATLAB function plots the contour lines of symbolic expression f(x,y) over the default interval of x and y, which is [-5 5].
