Hi Hans, No, I did not check this file but only update context Standalone. I guess this is not enough since the compilation does not work.

Hello Hans, The macro you wrote to draw the arrows of the vectors does not seem to work anymore. Thank you Fabrice

Did you check ou tthe latest meta-imp file? Alan and I added more and also changed the interface a little which might have consequences.

\useMPlibrary[mat]

% will be in meta-imp-mat.mkiv
