I need to report in the column Var4 of the table SimultedPoints the values of column Discharge of table Name_Code. All of the values of the table Name_Code are present in the table SimulatedPoints. I need to fill the cell arrays of Var4 with the Discahrge values if the Names and Codes matches in the two tables and with zeros if they don't.

E.g

in Var4{idxPoint=1} I should obtain a vector of length 148x1 filled with zeros but a discharge data in correspondence of the position of 7.8675e+04 in the cellarray SimulatedPoints.Codes{idxPoint}

for i=length(Name_Code)
    idxPoint=find(Name_Code.Name(i)==SimulatedPoints.Name(:))
    length_vector=SimulatedPoints.Codes{idxPoint,:};
    n=length(SimulatedPoints.Discharge{idxPoint});
    
    for j=1:length(length_vector)
        if length_vector(j)==Name_Code.Codes{i,:} 
            k(j)=Name_Code.Discharge{i}(j,1);
            SimulatedPoints.Var4{idxPoint}=k(j);
        else
            SimulatedPoints.Var4{idxPoint}k(j);
            k(j)=0;
        end
    end
end
