vfield_color

Plot a 2-D vector field, where color is defined by a colormap and indicates vector magnitude.

The function VFIELD_COLOR plots 2-D velocity vectors with colors defined by a colormap.

Syntax:
VFIELD_COLOR(X,Y,U,V,SCALE,CMAP)

Inputs:
X, Y Arrows origin, N-D arrays
U, V Current components, N-D arrays
SCALE Scalar value to set vector lengths
CMAP Colormap, N x 3 array of RGB values

Example:
image = zeros(100);
x = (rand(1,50) .* 80) + 10;
y = (rand(1,50) .* 80) + 10;
u = rand(1,50) .* 100;
v = rand(1,50) .* 100;
cmap = jet(64);
scale = 10;
vfield_color(image,x,y,u,v,scale,cmap)
