Details:
The scaling argument seems to have no effect when the vector field is
constant. Changing the fifth argument to quiver in the code below had no
affect on the plot.
% Range over which to plot field
range = [-5:.5:5];
% Create vector tail coordinate grid
[xx yy] = meshgrid(range);
% Toggle pair between 1 and 2 to select the u, v pair to plot
pair = 2;
u{1} = xx; v{1} = .4;
u{2} = .4; v{2} = .4;
figure(1)
% Vary the fifth arg between 0 and 1
% It has no affect on the second u, v pair above (pair = 2)
quiver(xx, yy, u{pair}, v{pair}, .6)
xlim([range(1) range(end)]);
ylim([range(1) range(end)]);
grid on
