How to increase Quiver_tri arrow length

%QUIVER_TRI(x,y,u,v,headsize,headangle,width,col)

can any body help with insight on how to increase the arrow head using Quiver_tri function.

say, quiver_tri (xx_, yy_, uu15_, vv15_,5,27.5,1,'k');

%quiver_tri(x,y,u,v,headsize,headangle,width,col)

Quiver_tri arrow length

When I tried, the arrow length is adjusted with gird number.

[x,y] = meshgrid(0:0.5:2,0:0.5:2);
u = cos(x).*y;
v = sin(x).*y;
figure
quiver(x,y,u,v)

[x,y] = meshgrid(0:0.2:2,0:0.2:2);
u = cos(x).*y;
v = sin(x).*y;
figure
quiver(x,y,u,v)

Thank you@ Kalyan AcharJya.

However, I want the quiver head modified to a reasonable size and this am not getting with quiver function, that was why I opted to used quiver_tri function. Though quiver_tri gave me the desired head size but a shorter quiver tail.

That was why I asked the question.
