Hi, suppose I have a custom color array:

c=[1 0 0
   0 1 0
   0 0 1]

Is there a way use the color array in a plot without looping? The following doesn't work:

plot(rand(100,3),'color',c)

Another option is to set the color after plotting via the cell array set syntax:

c = [...
 1 0 0
 0 1 0
 0 0 1];
h = plot(rand(100,3));
set(h, {'color'}, num2cell(c,2));

It requires an extra line of code, but I've always found this much easier than messing with default color order, hold settings, etc.
