This is a very informative video and is easy to understand, so could you please show us how to estimate the parameters of a system of equations like 2 or 3 or many? Thank you!
@@chemicalengineeringsolutio8927 this was very helpful for me.But the issue is I did this with SEIR model and fminsearch ,then it gives some errors.I am stucked with my research in that point .So can you help me if possible ?
Thanks for your video. That's helped me to understand the logic of parameter estimation. I have one question. I wrote the same code and run. But, I get the following error. Warning: Gradient must be provided for trust-region algorithm; using quasi-newton algorithm instead. > In fminunc (line 403) In uncontrainedoptimization (line 17) Solver stopped prematurely. fminunc stopped because it exceeded the function evaluation limit, options.MaxFunEvals = 300 (the default value). and I did not get the best fit with your estimation. Is there any adjustment that I must make in MATLAB? Thank you.
Thank you! sir,for this informative video and i have took help from your video to solve nonlinear ode system for 3 variables, but ,here, it is coming error. So please,may you provide code for solving 3 variable system.
How to find parameters a and b such that the sum of quadratic errors e=sum_i((ym_i-y(tm_i))^2) between measurements ym and model output y is minimal using optimizers such as fminunc and ODE. The model reads xt=[0 1; a b]*x; y=x; tm ym 0 1.0000 0.5000 0.6482 1.0000 -0.1047 1.5000 -0.6897
Can u pls tell how do i calculate service life? I mean if i've 3 parameters , from that how can i find service life of RC structure? Any link or code in MATLAB??
Best video so far on the whole internet. I am not exaggerating please!
Thankyou for providing such an informative video!
this video helped me sooooo much man
Thanks a lot for such a nice video. You did an excellent job. Make more videos

Nice video, It was very helpful. Greetings since Mexico
You're welcome! Happy to help :)

fminunc stopped because it exceeded the function evaluation limit,
options.MaxFunEvals = 300 (the default value).
and I did not get the best fit with your estimation. Is there any adjustment that I must make in MATLAB? Thank you.
Really Helpful ...Thanks
Hello sir
If possible make video on model reference adaptive control for 3 dof spherical articulated robotic manipulator
Could you please show a parameter estimation with an ODE-System?

The model reads
