Time-dependent parameter for ODE system

Hello,

suppose I have a system of ODEs for y1 and y2:

d/dt(y1) = a*f(t) - b*y1,

d/dt(y2) = m*y1 - n*y2,

where a, b, m and n are positive constants and f(t) is a time-dependent parameter.

The problem is that f(t) is available only as a vector (not an explicit function of t) on the same time scale as the one used for the ODEs solving.

How could I pass the corresponding value of f into the system of ODEs for the corresponding time?

Your suggestions would be greatly appreciated.

Many thanks,

Ildar

use interp1 to achieve this - an example of how to do this is here.

Thanks Stephan! It did work.
