matlab code for expressions

how do i write the code for following expression: y(n)=ramp(n)+x(n+5)+ramp(-n)

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

[Star Strider]

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?????

[saranya s]

Thanku so much for ur reply sir.. i tried in linespace(),i got the answer too.. but i want to make the expression or some equation to get this output.the x and y axis,elements value should be like 1,2,3...

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

[saranya s]

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

[Image Analyst]

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);
