I am getting an error when using the merge function with two different estimated greybox models with different data, but with the same structure (function). The error is as following,
_Error using idParametric/merge (line 44)
Inner matrix dimensions must agree._
The code is quite simple. I will paste the most important parts,
opt = greyestOptions('DisturbanceModel','Estimate')
sys = idgrey('myfunc_greybox',var,'c',aux,0)
data = iddata(yout(:,1:2),yout(:,3),0.002)
m1 = greyest(data,sys,opt)
I use it twice and then combine the 'm' variable:
Myfunc_greybox() is a function in which I declare the space state structure I'm working in. I don't know if it's relevant.
Thank you in advance. Best regards.
PS: I've tried with merge with ssest, iddss with parameters restrictions and it worked fine. But I'm interested in the parameters that greybox could estimate, as well as the variances combination.
