hi
I have (bbhat ) size(150,3) and (vvhat) size(150,3)
both vectors have the same size
I tried this:
for ii = 1:length(bbhat);
quiver3(bbhat(ii,1),bbhat(ii,2),bbhat(ii,3),vvhat(ii,1),vvhat(ii,2),vvhat(ii:3),0.5);hold on
end
I got this error
Error using quiver3 (line 43)
V and W must be the same size.
pls help

size(bbhat)
ans =
105 3
>> size(vvhat)
ans =
105 3

There is a typo error ..you have used vvhat(ii:3) instead of vvhat(ii,3)
for ii = 1:length(bbhat);
quiver3(bbhat(ii,1),bbhat(ii,2),bbhat(ii,3),vvhat(ii,1),vvhat(ii,2),vvhat(ii,3),0.5);hold on
end
Also note that you need not to use loop for this..you should plot all at once.
quiver3(bbhat(:,1),bbhat(:,2),bbhat(:,3),vvhat(:,1),vvhat(:,2),vvhat(:,3),0.5);hold on
