Dear all,
My question may soud elementary:

After using eigensystem to obtain eigenvector , how do I save the output as stata data?

thanks,

Thank you !

Please see my code below on a pretend data. I want to output the eigenvector X after running matrix symeigen.


matrix a=(1,2\3,4)

matrix list a

* make it symmetric

matrix b=a'*a

matrix symeigen X L = b

matrix list X

getmata X

** error : vector or matrix X not found

What did I do wrong?

You can figure this out for yourself if you read the help for getmata. The section titled "Definition of getlist for use with getmata" has four basic examples. Your current syntax corresponds to none of them.
