These arrays must be the same size, monotonic,and 3-D plaid (such as the data produced by meshgrid).• Cx, Cy, Cz define the location of the cones in vector field.coneplot(U,V,W,Cx,Cy,Cz) (omitting the X, Y, and Z arguments) assumes[X,Y,Z] = meshgrid(1:n,1:m,1:p) where [m,n,p]= size(U).coneplot(...,s) MATLAB automatically scales the cones to fit the graph andthen stretches them by the scale factor s. If you do not specify a value for s,MATLAB uses a value of 1. Use s =0 to plot the cones without automaticscaling.coneplot(...,'quiver') draws arrows instead of cones (see quiver3 for anillustration of a quiver plot).coneplot(...,'method') specifies the interpolation method to use. methodcan be: linear, cubic, nearest. linear is the default (see interp3 for adiscussion of these interpolation methods)h = coneplot(...) returns the handle to the patch object used to draw thecones. You can use the set command to change the properties of the cones.Remarksconeplot automatically scales the cones to fit the graph, while keeping themin proportion to the respective velocity vectors.2-95
