Index exceeds matrix dimensions error

I am trying to perform optimisation using genetic algorithm and when I start the solver, I get this error => "Index exceeds matrix dimensions"

This is my code

%photon current estimation

function result = PhotonFcn(x)
Iph = x;
Isc = 5.98;
Ki = 0.0035;
Top = 273 + 46;
Trf = 273 + 25;

result = (Isc + Ki(Top - Trf)) - Iph;
end

Please help!

Typo, you forgot the *:

result = (Isc + Ki *(Top - Trf)) - Iph;

You made a typo, you forgot the *:

result = (Isc + Ki *(Top - Trf)) - Iph;
