This cannot wok for several reasons, inclusing typos, and is not 
reproducible for us given we do not know about "mata".

Anyway, fixing your typos and the specification of the argument "log", 
we get:

matplot(mata, log="y", type = "l", col = "red")

and overlay the red with yellow lines, although it makes no sense:

matplot(mata, type = "l", col = "yellow", add = TRUE)
