Details:
If no marker is specified, then the arrows are at the head of the vectors. For
example,
quiver(1:2,3:4, -2:-1,1:2)
quiver(1:2,3:4, -2:-1,1:2, 'r')
quiver(1:2,3:4, -2:-1,1:2, 'b--')
quiver3(1:2,3:4,5:6, -2:-1,1:2,0:1)
quiver3(1:2,3:4,5:6, -2:-1,1:2,0:1, 'r')
quiver3(1:2,3:4,5:6, -2:-1,1:2,0:1, 'b--')
But if a marker is specified, then the markers are at the tail of the vectors.
For example,
quiver(1:2,3:4, -2:-1,1:2, 'r-v')
quiver(1:2,3:4, -2:-1,1:2, 'b--o')
quiver(1:2,3:4, -2:-1,1:2, 'b-o','filled')
quiver3(1:2,3:4,5:6, -2:-1,1:2,0:1, 'r-v')
quiver3(1:2,3:4,5:6, -2:-1,1:2,0:1, 'b--o')
quiver3(1:2,3:4,5:6, -2:-1,1:2,0:1, 'b-o','filled')
The docstring of quiver/quiver3 says that
The style to use for the plot can be defined with a line style
STYLE of the same format as the 'plot' command. If a marker is
specified then markers at the grid points of the vectors are drawn
rather than arrows. If the argument "filled" is given then the
markers are filled.
In this above paragraph, what does "the grid points of the vectors" mean?
Does it mean the head or the tail of the vectors?
