I have a time vector which I have attached in a .mat file.

diff(time) generates the following error: Subscript indices must either be real positive integers or logicals.

time is a vector, it does not contain values to be interpreted as indices. Why is this occurring & how can I correct it?

You have a variable named "diff" somewhere in your workspace. MATLAB is interpreting diff(time) as an attempt to index it.

Solution: clear it or rename it to something else.
