Syntax:
HANDLE = VFIELD(X,Y,U,V,VARARGIN)

Inputs:
X, Y Arrows origin, N-D arrays
U, V Current components, N-D arrays
VARARGIN:
C, patches CData
'color', <color> line/patch color [ 'k' ]
'fill', [ {0} | 1 ], fill arrows tip
'tr', <val>, tip length with respect to intensity or absolute length if is a string [ <value> <value as string> {0.1} ]
'fi', <deg>, tip angle [ 30 ]
'z', <val>, z level, value or array size x, y, u and v [ 0 ]

The screenshot was created with:

[x,y] = meshgrid(-2:.2:2,-1:.15:1);
z = x .* exp(-x.^2 - y.^2);
[u,v] = gradient(z,.2,.15);
vfield(x,y,.3*u,.3*v,z), colorbar
axis equal
