Hi,

I am trying to run a code for sensitivity analysis on initial conditions and parameters of a process. To evaluate the different inputs I use a for loop and I solve an ODE in each iteration. The problem is that some of the combination of parameters and initial conditions cannot be solved and, when this happens, ode45 (and ode15s) stops the script. I really would wish that the for loop could keep on running after storing a warning output from the odesolver. Do you know if this is possible? I include a pseudocode of the script:

    % mxn A matrix contaning m sampling combinations of n input parameters
  for i=1:m
       input=A(i,:)
       solution(i)=odesolver(@function,t,input)
  end

So the question is if I could do something so that the for loop keeps running even if the odesolver gives an error message. Thank you,

Miguel
