Hello all,
I have this function y of t, and I want to find the following definite integral (I am using the LateX syntax):
\int_{kT}^{(k+1)T}y(t)\,dt
for k=0,1,..., K-1. How can I do this in MATLAB?
Note: K is a very large number, and hence, I need an efficient way of doing the integration for all k other than for-loop approach.
Thanks

I have the vector dCP which consists of samples at t=n*Ta. I want to transmit it over a channel which scales/shifts these samples. That is why I am using the interpolation. At the receiver I want to use matched filtering to extract the samples again, which involves the integration above.

Someone told me I can do this by interpret integration as summation (integration by definition).
