How to solve this issue Variable ‘X’ is not fully defined on some execution paths.

Dear All,

I have a code into a MATLABFUNCTION block of Simulink that jump out this error message “

Variable ‘CONDICIONTRAMO’ is not fully defined on some execution paths. Function ‘Battery_Control/Function_Cruz_v2’ (#25.1881.1895), line 57, column 12: “CONDICIONTRAMO” Launch diagnostic report.”

Anyone of you can help me out to find the way to solve this ? Please.

if SOC>=SOC_Seg   
SOC_CC=0;
Bat_charge=0;
return
else
if SOC>=SOCint
SOC_CC=1;
Bat_charge=0;
end
if SOC<=SOCint

if (top>=8)||(top<=9) && Power_PV>W_demand
CONDICIONTRAMO = 1;
disp('Llano 1 de 8 a 9')
elseif (top>=8)||(top<=9) && Power_PV=10)||(top<=13) && Power_PV>W_demand
CONDICIONTRAMO = 3;
disp('Punta 1 de 10 a 13')
elseif (top>=10)||(top<=13) && Power_PV=14)||(top<=17) && Power_PV>W_demand
CONDICIONTRAMO = 5;
disp('Llano 2 de 14 a 17')
elseif (top>=14)||(top<=17) && Power_PV=18)||(top<=21)&& Power_PV>W_demand
CONDICIONTRAMO = 7;
disp('Punta 2 de 18 a 21')
elseif (top>=18)||(top<=21)&& Power_PV=22)||(top<=23)&& Power_PV>W_demand
CONDICIONTRAMO = 9;
disp('Llano 3 de 22 a 23:59')
elseif (top>=22)||(top<=23)&& Power_PV=24)||(top<=8) && Power_PV

Insert a definition of CONDICIONTRAMO = -1 (or NaN, or 12) either on top of the code, before the IF branchs, or in a finaly else branch:

But then Bat_charge is not defined in all branchs. Add a default value for this variable also.

By the way, the Switch/Case-Block is hard to read. Maybe this is tougher:

SOC_CC     = SOC_CC_V(CONDICIONTRAMO);
Bat_charge = Bat_charge_V(CONDICIONTRAMO);
