Running a Two One-Sided Tests (TOST) for Equivalence

I am doing some statistics on two datasets (basically, two vectors of values). I want to test these two datasets for equivalence. The appropriate way to do this is with the "Two One-Sided Tests (TOST)" method. This method is described on the fourth page of this document: http://homepage.stat.uiowa.edu/~rdecook/stat6220/Class_notes/equivalence_testing.pdf

Unfortunately, I cannot find any documentation on how to do this in Matlab. Are there any stats people here who could help figure out the appropriate code to do this?

I know this question was submitted a year ago, but I thought I'd contribute my 2 cents anyways.

As far as I know, Matlab does not have a built-in function that will perform the TOST method (or any other method of testing for equivalence, for that matter). To address this, I have created a simple function based on Roger et al, 1993, entitled TOST.m on the Matlab file exchange. You can access the code here:
