Conformability error, r(503)

[Ndm Sanchez]

Hi everyone, I have a problem when I want to input a matrix in Stata. First I local some results and then I want to construct my matrix but Stata show me r(503). Any help would be appreciated, thanks. In the figure you can see the command that I used.

This is Statalist's Mata Forum, which is used for questions about Stata's Mata language, as discussed in help mata rather than Stata's matrix commands described in help matrix.
