Using RowFun as LookUp

Hello everybody,

i worked today the first time with the functions "RowFun" and it works really fine and it is faster then with a For-Loop.

daten.FINART  = rowfun(@convertFinArt,params)

My problem is that i have to load a table for my lookUp Function.

function FinArt = convertFinArt(TAFIC, TART)    
        load('TAFIC_Tab.mat')  
        FinArt = TAFIC_Tab.FinArt(TAFIC_Tab.TAFIC==TAFIC & (TAFIC_Tab.TarifArt == TART|TAFIC_Tab.TarifArt ==0));
end

Is there a possibility to load the Table once and to transfer this table with params?

params =  table(daten.TAVE,daten.TAVE_NR,'VariableNames',{'TAVE','TAVE_NR'})

The problem and my question is how, cause the params and this table doesn't fit.

Thank you for your help.
