Title

spmat eigenvalues -- Add eigenvalues of the
spatial-weighting matrix W to an spmat object

Syntax

spmat eigenvalues objname [, options]

eigenvalues(vecname) Mata vector containing eigenvalues

replace replace existing eigenvalues

Description

spmat eigenvalues calculates the eigenvalues of the spatial-weighting
matrix W contained in the spmat object objname and stores
them in objname. Having precomputed eigenvalues in objname will
speed up the estimation command spreg ml.

Options

eigenvalues(vecname) specifies a Mata vector containing the
eigenvalues of W. The vector must be stored as a
complex rowvector.

replace allows the existing eigenvalues to be overwritten.

Example

Setup

. spmat use cobj using pollute.spmat

Add eigenvalues to the spmat object cobj

. spmat eigenvalues cobj
