Discrete frequency sweep data for system identification.

Hi guys. I would like to perform a system identification on a mechanical system, in which i need som input data to perform this frequency sweep.

The data should be discrete but still with high enough samplerate such that alliasing doesn't occur.

Is is possible to get it using Matlab, if so than how?...

Here is a Matlab script for generating a sine sweep. https://vibrationdata.wordpress.com/2014/02/14/webinar-unit-3-sine-sweep-vibration/

Thanks for the link.. It doesn't seem to generate any output data or am I using it incorretly?
