I have a graph with weights associated to the edges. I plot the edges as lines and I would like to assign colors in a continuous colormap to each edge. Does any one know how to do it? Thanks.

Do you mean something like this?
x = 1:10;
y = rand(1,10);
w = 1:10; % weights
patch([x NaN],[y NaN],[c NaN], 'edgecolor', 'interp', 'facecolor', 'none')

Yes, "patch" seems the right command for my problem. However, I have two lines crossing with each other. For "Patch", I have to divide these two lines into four lines. Is there any way to keep two lines? I want to keep the color the same for each line, even though it is crossed by other line. Thanks.

patch would not require that you divide the lines if you do not want the crossing to influence the coloring.
