I have a MATLAB function that does some calculations and gives 3 outputs which will be used again as an input to this function. This function is like

function  [out1,out2,out3]=LoopFunction(out1,out2,out3,param1,param2,param3,param4,input,param5)
% does something...

input variable will be used as a step function and param inputs are just constants.

Normally in MATLAB i can do something like this and do what i want just fine

param1 = 1 ; param2 = 1; param3 = 1; param4 = 1 ; param5 = 1;
out1_init = 1;
out2_init = 1;
out3_init = 1;
for i=1:1000
    if i == 1
        [out1,out2,out3] = LoopFunction(out1_init,out2_init,out3_init,param1,param2,param3,param4,1,param5)
    else
        [out1,out2,out3] = LoopFunction(out1,out2,out3,param1,param2,param3,param4,1,param5)
    end
end

But i don't know how to do this on Simulink. Is there any way to implement this? So far i have tried something as belows but i cannot find a way to initilize out1 , out2 and out3.
