set the initial values using an exit matrice when using the command of optimize_init_params

[masenry miao]

Hello, I want to do the optimization with the loop method. but I am not familiar with mata :

the following is the code:

optimize_init_params(S, rowvector initialvalues)

in my data ,the ols_26 is a matrice ( 1*n)

so I run the code : optimize_init_params(S,ols_26) in mata.

but stata shows these errors:

optimize_init_params(): 3202 ols_26[0,0] found where rowvector required
DLW(): - function returned error
<istmt>: - function returned error

Thank you for your help.

From the question, it is a little unclear what exactly is going on. Do you have a more thorough decription of your objective function and how you have defined it?

Best,

Have you tried passing a row vector to the second argument of the function?

optimize_init_params(): 3202 ols_26[0,0] found where rowvector required

Seems to be saying you cannot pass a matrix to the second argument. Maybe placing your starting values in a row vector will solve the problem for you?
