# not a function file

numParts=[numPart, numPart, numPart, numPart, numPart, numPart]';
numTreats=[numTreat1; numTreat1; numTreat2; numTreat2; numTreat3; numTreat3];

treats=[treat1; treat1; treat2; treat2; treat3; treat3];

anovan(value, [numParts, numTreats])

My goal is to calculate 2-way anova tests for Gauge R&R study. In my experience, anovan always returns Fval=0.000 and p-value NaN, for every input value. This behaviour was also found when inputting dataset copied from textbooks or literature. I have written some lines to provide an example without copying copyrighted material. All the datasets I can generate with the lines above were checked by me against results calculated with R software, and in every case I am getting a result different from Fval=0.000.
