EXERCISE 1 Write a Matlab script file to plot three functions on one graph. Plot y = sin(x) in red, y = sin(2x) in black, and y = sin(3x) in green, with x ranging from -16 to 16. Change the marker...

How can I get codes for this problem by using GNU Octave?

Note: (It is up to you to choose the marker style)
