MATLAB: Plot 2D vector field

I have a table T of four columns x,y,u,v,

where x and y are the coordinates

and u and v are the values of the x and y components, respectively.

Thus, T represents a two-dimensional vector field.

For example, let

1 3 -1 -1

1 4 0.500000000000000 -0.500000000000000

2 3 -0.250000000000000 0.250000000000000

2 4 0.100000000000000 0.100000000000000

I want to plot a 2-D vector field from this table!!!

I tried using the function:

coneplot(T)

but became the following error message:

??? Error using ==> coneplot>parseargs at 365

Wrong number of input arguments.

Error in ==> coneplot at 64

[x y z u v w cx cy cz s color quiv method nointerp] =

parseargs(nargs,args);

It seems that coneplot works only for 3-D.

Can someone tell me how to change this command line?

Thank you
