error message ()-indexing must appear last in an index

Hi,

I have the code below and when I try to run it, I get the error message ()-indexing must appear last in an index expression

V= zeros(size(data17,1),1);

Kappa=1.15;
Theta=0.04;
Sigma=0.39;
Rho=-0.64;
Tau=30/360;

V=(exp(Kappa*Tau).*((data17(:,8)/100)^2)*Kappa^2*Tau+Theta(exp(Kappa*Tau)(1-(Kappa*Tau))-1))/((exp(Kappa*Tau)-1)*Kappa)

doe anybody have an idea what is missing or what I am doing wrong?

MATLAB does not recognize

(A+1)(B+2)

as multiplication of A+1 and B+2. You need, for example

(A+1)*(B+2).

Guessing a bit, but I think you want a multiplication sign after the Theta, and another after

exp(Kappa*Tau)

Otherwise it looks like you are indexing into an array Theta, and then indexing again.

pefect, that waas exactly the problem, thanks
