Lets say i have created a column vector c = [ N x 1 ] and my time vector has the same dimensions.

I want to create a function f(t) in which f(fstep) = c(cstep) where cstep is integer and fstep maybe not.

( for example f(0)=c(0), f(0.1)=c(1), ... f(10)=c(100))

As a result i will be able for example to do the calculation sin(t)*f(t).

Thanks
