MATLAB: Declare array in Simulink

arraydemuxsimulink

I have a function on Simulink that copy an in variable to another according a number (such as a DEMUX, but selectable)
 % code
function [device,Var_RX1, Var_RX2, Var_RX3, Var_RX4, Var_RX5, Var_RX6, Var_RX7, Var_RX8, Var_RX9, Var_RX10]  = fcn(device, Var_RX)
Var_RX1 = zeros(50,1,'single');
Var_RX2 = zeros(50,1,'single');
Var_RX3 = zeros(50,1,'single');
Var_RX4 = zeros(50,1,'single');
Var_RX5 = zeros(50,1,'single');
Var_RX6 = zeros(50,1,'single');
Var_RX7 = zeros(50,1,'single');
Var_RX8 = zeros(50,1,'single');
Var_RX9 = zeros(50,1,'single');
Var_RX10 = zeros(50,1,'single');    
    if (device == 1)
        Var_RX1 = Var_RX;
    elseif (device == 2)
        Var_RX2 = Var_RX;
    elseif (device == 3)
        Var_RX3 = Var_RX;
    elseif (device == 4)
        Var_RX4 = Var_RX;
    elseif (device == 5)
        Var_RX5 = Var_RX;
    elseif (device == 6)
        Var_RX6 = Var_RX;
    elseif (device == 7)
        Var_RX7 = Var_RX;
    elseif (device == 8)
        Var_RX8 = Var_RX;
    elseif (device == 9)
        Var_RX9 = Var_RX;
    elseif (device == 10)
        Var_RX10 = Var_RX;
    end
end
The problem is that when the function is call I have to declare the variables (Var_RX) as zeros otherwise the follow problem occurs: "Output argument 'Var_RX1' is not assigned on some execution paths."
There's a way to declare those arrays out this function and just start the value in the beginning of the program?

I solved my problem using simulink-if's blocks, then the value isn't replaced every read/write.
