Retrieving boundary nodes matrix

Please login with a confirmed email address before reporting spam

Hello,
Does any one know if it is possible to get a fem matrix corresponding to boundary nodes? That is, suppose that I define a variables u=z (u is the solution) on part of the boundary, is it possible to get the matrix corresponding to this variable using, for instance, mphstate?

In the examples in the documentation it is shown how to get A and B from z'=Az+Bu, where u is a parameter. But what if u is a variable defined on the boundary?
