File Information
Description

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)
