Why does the QUIVER command in MATLAB display the wrong vector length?
显示 更早的评论
When I execute the following code in MATLAB:
quiver(0,0,3,0);
the resulting plot does not display an arrow from (0,0) to (3,0).

This enhancement has been incorporated in Release 2006a (R2006a). For previous product releases, read below for any possible workarounds:
The QUIVER function in MATLAB autoscales vectors it draws, as described in the documentation.
As this indicates, you can obtain correct lengths by using a fifth argument, a scaling parameter. The following code displays the expected arrow from (0,0) to (3,0):
quiver(0,0,3,0,0);
quiver(0,0,3,0,'AutoScale','off')
Alternatively, one of the following three commands will work:
quiver(0,0,3,0,1);
quiver(0,0,3,0,'AutoScaleFactor',1)
The latter 2 are autoscaled and a scaling factor of 1 is applied.
