fitlme function - does it support complex number input?

I have two angular variables X and Y which I want to relate through a linear mixed-effects model (i.e. fixed effects and random effects). Both X & Y are vectors, with dimension N x 1. Since they are angular variables, I represent each of them as complex numbers, using the operations:

Xc=exp(1i*X); 
Yc=exp(1i*Y);

Can I now use these two variables as input (through a table) to the fitlme function in MATLAB? The fitlme function in turn calls the LinearMixedModel.fit function.

Just for info: I tried relating complex variables through the 'regress' MATLAB function and it works fine.

Any help much appreciated!
