I am building a matlab GUI to retrieve an average PnL number from a 1047*1 double cell string called pnl_P1 into edit text window called (function Average_PnL_Pair_1_Callback(hObject, eventdata, handles)). What is the simplest or very simple way to do this?

Do you want
mean(cellfun(@str2double, pnl_P1))?
