doc plot
will learn you this:
h = plot(_) returns a column vector of lineseries handles, where h contains one handle per line plotted. When multiple lines are present, you can make changes to properties of a specific line by specifying its handle.
so use this handle in combination with set There is even a complete example worked out showing to do what you want (Change Line Properties Using Handles) but you can also automize this in a for loop when you store your colors and linestyles in a matrix
