I am trying to figure out how to plot a line segment using a specific color vector, like [1 0 0]. I typed in the command window plot([0 1], [0 1], 'g') and this plots a green line segment from the point 0,0 to 1,1. However, when I type in the code plot([0 1], [0 1], [1 0 0]), I get the following error message:
Error using plot
Data must be a single matrix Y or a list of pairs X,Y.
I also tried typing in ['1 0 0'] for the color vector and got a different message
Error using plot
Error in color/linetype argument.
I feel like I'm missing something obvious but not sure what it could be. Please help!

Hi Kelsey,
You need to use the attribute 'color'. See the following example:
plot([0 1], [0 1], 'color', [1 0 0])
