What is "ramp()"? A variable or a function?

Ramp is a Simulink block. I’m not certain that it has a function representation.
@saranya s — What do you want to do? What is ‘n’ and what do you want ‘y(n)’ (apparently a function) to produce?

How many elements are between 0 and 5 and between 8 and 15? How many do you want to have? Have you simply tried linspace() or the colon operator?????

Would you like to use the sawtooth() function in the Signal Processing Toolbox?

i wanna produce ramp signal by using either ramp comment or r(t)..is it possible?

I assume you mean command rather than comment.
I don't have the ramp() command/function. You can use linspace
y = linspace(startingValue, endingValue, numPoints);
