i am solving a systm on ODEs and need to alter rate constants to realise a biological function.
t = [500 1500]
T = [0 3000]

Hi Hetavi,
From what I understand you want to solve a time-dependent ODE where you need to alter the rate constants based on the time.
You can refer to the following example for understanding how to solve a time-dependent ODE :
As for implementing a time-based rate constant, you can incorporate that within the definition of the ODE itself in the following way:
function dydt = myODE(t, y, params)
% Check if the current time is within the timespan to change parameters
if t >= 500 && t <= 1500
k = params.changedRate; % Use the changed rate constant
else
k = params.normalRate; % Use the normal rate constant
end
dydt = ...; % Replace with your actual ODE system
end
Best,
Umang
