Title

    spmat getmatrix -- Copy a matrix contained in an spmat object to a Mata
                         matrix


Syntax

        spmat getmatrix objname [matname] [, options]


    options              Description
    -------------------------------------------------------------------------
      id(vecname)        name of a Mata vector to contain IDs
      eig(vecname)       name of a Mata vector to contain eigenvalues
    -------------------------------------------------------------------------


Description

    spmat getmatrix copies the spatial-weighting matrix W contained in the
    spmat object objname to the Mata matrix matname.  The place identifiers
    and the eigenvalues of W can be optionally saved to Mata vectors.


Example

    Setup
        . spmat use cobj using pollute.spmat

    Copy the contiguity matrix contained in the spmat object cobj to the Mata
    matrix mymat
        . spmat getmatrix cobj mymat

    Copy the eigenvalues contained in the spmat object cobj to the Mata
    vector myeig
        . spmat getmatrix cobj, eig(myeig)
