Error: Index exceeds matrix dimensions.

Hi I am getting this error "Index exceeds matrix dimensions" for the following:

c(2:T-1)=(epsilon(2:T-1)'.*n(2:T-1))*Fn+(1+Fk)*k(1:T-2)-k(2:T-1);

How can I solve it? thanks

One needs the content of the respective variables.

[dpr]

the values are these:

k=[k0 0.01*ones(size(1:T-2))]

n=ones(size(1:T-1))

epsilon(1:T,1)=2

[Sargondjani]

it looks fine, but you should check the sizes of epsilon, n and k

you can use 'dbstop' so matlab stops just before this command, then you can see in the workspace what their size is

This is a task for the debugger, while it is impossible to guess the reason of the problem based on the information you have posted.

Either use dbstop if error or set a breakpoint in the M-file directly. Then inspect the sizes of the variables:

disp(T);  
disp(size(epsilon))
disp(size(n));
disp(size(k))

Then you will find out, which of the variables has an unexpected size.
