Hello everyone,
I used lsqnonlin to find unknown parameters of an ODE. However, when i run the script, it is taking a long time. Until now, it tooks 25 min and it's the first time i encounter this !
The system i'm solvin consists of 3x3 matrix.
Do you think the time for this is reasonable or there is something going wrong ???
I searched a lot on how to know whether the script is stuck somewhere but i didn't succeed.
Based on your experience, is there any method to know where the code is stuck ?
