MATLAB: Fitlme “Index exceeds matrix dimensions.”

fitlmeindex exceeds matrix dimensionslinearmixedmodels

Hi, I'm trying to use the new fitlme bult-in function (R2015a) and it keeps going on an error:
Index exceeds matrix dimensions.
Error in classreg.regr.LinearLikeMixedModel.makeSparseZ (line 1312)
                idxr     = accumarray(subs,vals(I),[],@(x) {x});
Error in LinearMixedModel/fitStandardLMEModel (line 1225)
        Zs = LinearMixedModel.makeSparseZ(Z,q,lev,Gid,N);
Error in LinearMixedModel/fitter (line 822)
        model.slme = fitStandardLMEModel(model);
Error in classreg.regr.FitObject/doFit (line 220)
            model = fitter(model);
Error in LinearMixedModel.fit (line 2395)
        model = doFit(model);
Error in fitlme (line 224)
    lme = LinearMixedModel.fit(ds,formula,varargin{:});
Also, running the fnuction takes too long (the error appears after several minutes of wating) and consume a lot of RAM. This is the line I'm running:
lmm1 = fitlme(datos_tabla, 'E1_T1 ~ pred + (1|SUJ)' );

Hi Bruno,
This doesn't look like the intended behavior but it is difficult to say why you are getting that error. Could you post your data that reproduces the problem?
