Ops.strucMatrix: Structured sparse matrix multiplication (and other binary...

In stevencarlislewalker/lme4ord: Generalized Linear Mixed Models with Flexible (Co)Variance Structures

Description

Because of the marginal summations involved, the results of a matrix multiplication of strucMatrix objects is not profitably stored as a strucMatrix. Therefore, the output is a sparseMatrix.

Usage

## S3 method for class 'strucMatrix'
Ops(e1, e2)

## S4 method for signature 'strucMatrix,missing'
crossprod(x, y = NULL, ...)

## S4 method for signature 'strucMatrix,missing'
tcrossprod(x, y = NULL, ...)

## S4 method for signature 'strucMatrix,strucMatrix'
crossprod(x, y = NULL, ...)

## S4 method for signature 'strucMatrix,strucMatrix'
tcrossprod(x, y = NULL, ...)

Arguments

e1,e2	strucMatrix objects
x,y	strucMatrix matrix objects
...	not used (only for consistency with generic)

Note

The * operator is matrix multiplication, not element-wise multiplication.
