function linmeasure=log2lin(value,scaleinfo)

% wandelt einen Wert entsprechend den Angaben in scaleinfo wieder 
% in den ursprünglichen linearen Wert zurück

from=scaleinfo.from;
to=scaleinfo.to;
steps=scaleinfo.steps;

a1=log(from);
a2=log(to);
st=(a2-a1)/(steps-1);

linmeasure=log(value/from)/st+1;
