Adding a vector in a system of differential equations

I have a system of odes to be solved. The problem is that one of the odes contains iapp, which is a vector (same size as the time vector) i have from experimental data.
[time,output]=ode113('DiffEquations',time,init);
with:
function [output] = DiffEquations(time,init)
% defining variables and constants ...
% output(1,1)=....
% output(2,1)=(....
output(3,1)=(-iNa-iK+iapp)/C;
end
How should i input this vector in the function?

One way is to create a function handle to pass in the extra parameters. E.g.,
function [output] = DiffEquations(time,init,iapp) % <-- add iapp to the input argument list
Then in your calling code:
[time,output]=ode113(@(t,y)DiffEquations(t,y,iapp),time,init); % <-- function handle with iapp

If you don't know, then that means you don't understand your own set of odes. Is iapp perhaps a time sequence of values that you would need to interpolate? Again, we are guessing here until you can post the odes for us to look at.
