quiver3
Three-dimensional velocity plotquiver3(Z,U,V,W) quiver3(X,Y,Z,U,V,W) quiver3(...,scale) quiver3(...,A three-dimensional quiver plot displays vectors with components (u,v,w) at the points (x,y,z).LineSpec

) h = quiver3(...)
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(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(...,scale)
automatically scales the vectors to prevent them from overlapping, 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
)
specify line type and color using any valid line specification.
quiver3(...,LineSpec,
'filled')
fills markers specified by LineSpec
.
h = quiver3(...)
returns a vector of Line handles.
