AOC tool in Matlab to create an ANCOVA

Hello,

I am trying to use the 'aoc tool' in MATLAB to create an ANCOVA model with 3 independent variables, one dependent variables, and one covariate. The help toolbox for this function isn't very clear on how to add the covariate. Could someone please help me on how to set this up with an example? Thank you!

The aoctool() only allows for one grouping variable. Instead, anovan() might be an option for what you're describing.

anovan() is an n-way analysis of variance allowing for multiple grouping variables. When at least one of those grouping variables are labeled as a continuous variable, an ANCOVA is performed (Matlab calls it ANOCOVA, same thing).

An example of this useage is found here in Matlab's documentation.
