plotting flow fields

[MeteoMedic85]

Hi,

I wrote the following MATLAB script to describe a flow pattern. What I'd like to do is plot this as a vector field if I could. A is the u-component and B is the v-componenet. But I'm not sure how to correctly call "quiver" to plot this flow given the way I wrote the script. Thanks much for any suggestions.

t = [0:359];



x = (-1)*35*sind(t);

y = 35*cosd(t);



m = (y./x);



a = sqrt(1225./(1.+(m.^2)));



for j = 1:180

A(j) = -a(j);

end

for j = 181:360

A(j) = a(j);

end

for k = 1:270

B(k) = A(k+90);

end

for k = 271:360

B(k) = A(k-270);

end

for l = 1:360

B(l) = B(l) + 20;

end
