how to solve definite integrals in matlab

[Walter Roberson]

Is Grel constant in tau? If so then it is trivial to integrate

[Siva nanda Reddy]

It is not constant in tau

[Walter Roberson]

What is Gtel or Grel (I cannot quite tell what the characters are) ?

When I look at your equation it looks to me as if you are doing a convolution.

[Siva nanda Reddy]

yeah...its is a convolution

[Bjorn Gustavsson]

But since it is a convolution of the function Grel with a constant you only have a basic integral, just do a simple change of variables and you have a simple integral; seems like a natural first step...

You have the quadgk, integral, et al. functions for numerical integration. If you have access to the symbolic toolbox you and want an analytical solution you might have success with the int function. Check the help-documentation for those and see if they give you what you want.
