Hi, I have a group of data with one continuous dependent variable, a categorical independent variable with 3 levels, and a categorical covariate with 2 levels. I was trying to run the ANCOVA test in matlab, but from what I've learned, matlab only allows continuous covariate. I was wondering is there a way to run ANCOVA test with a categorical covariate?
Thank you!

It doesn't really make sense to run ANCOVA with a categorical covariate. Instead, think of the categorical covariate as another independent variable and analyze your DV with a 2-factor ANOVA (here, 3x2). This ANOVA will give you information about the 2-factor interaction as well as the main effect of your categorical covariate. The ANCOVA would only give you information about the covariate's main effect.
