Syntax

quiver3(x,y,z,u,v,w) quiver3(z,u,v,w) quiver3(...,scale) quiver3(...,LineSpec) quiver3(...,LineSpec,'filled') quiver3(axes_handle,...) h = quiver3(...)

Description

A three-dimensional quiver plot displays vectors with components (u,v,w) at the points (x,y,z).

quiver3(x,y,z,u,v,w) plots vectors with components (u,v,w) at the points (x,y,z). The matrices x,y,z,u,v,w must all be the same size and contain the corresponding position and vector components.

quiver3(z,u,v,w) plots the vectors at the equally spaced surface points specified by matrix z. quiver3 automatically scales the vectors based on the distance between them to prevent them from overlapping.

quiver3(...,scale) automatically scales the vectors to prevent them from overlapping, and then multiplies them by scale. scale = 2 doubles their relative length, and scale = 0.5 halves them. Use scale = 0 to plot the vectors without the automatic scaling.

quiver3(...,LineSpec) specifies line type and color using any valid LineSpec.

quiver3(...,LineSpec,'filled') fills markers specified by LineSpec.

quiver3(axes_handle,...) plots into the axes with the handle axes_handle instead of into the current axes (gca).

h = quiver3(...) returns a vector of line handles.

Examples

Plot the surface normals of the function .

[X,Y] = meshgrid(-2:0.25:2,-1:0.2:1);
Z = X.* exp(-X.^2 - Y.^2);
[U,V,W] = surfnorm(X,Y,Z);
quiver3(X,Y,Z,U,V,W,0.5);
hold on
surf(X,Y,Z);
colormap hsv
view(-35,45)
axis ([-2 2 -1 1 -.6 .6])
hold off
