WebWhen scale is a positive number, the quiver3 function automatically adjusts the lengths of arrows so they do not overlap, then stretches them by a factor of scale.For example, a scale of 2 doubles the length of arrows, and a scale of 0.5 halves the length of arrows.. When scale is 'off' or 0, such as quiver3(X,Y,Z,U,V,W,'off'), then automatic scaling is disabled. Webcontour (u,v,z,n)是画等值线. 其第四个参数是控制等值线的值的. 如果n是一个标量，那么解释为等值线的条数例如. contour (u,v,z,20)那么它会根据数据的范围画出20条等值线. 如果n是一个向量，那么解释为需要等值线的值，例如. contour (u,v,z, [1 2 3 4])会画出z=1,2,3,4四个值 ...

WebFeb 10, 2024 · Extracting data from contour plot. I want to extract the data in a contour plot that I have, especially the maximum number of (x,y) co-ordinates that make up the entire contour. Any help is appreciated. Thank you. For the max just use: max_num_coords = max (c (:,1)); if you want the total number you would make loop.
Webcontour (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,Y,Z) specifies the x and y coordinates for the values ...
