rbindSM: "row bind" two sparse matrices

Description

rbindSM: "row bind" two sparse matrices

Usage

rbindSM(SM1, SM2, SMM = "CRI", ZINDEX = FALSE)

Arguments

SM1	First sparse matrix object
SM2	Second sparse matrix object
SMM	Sparse matrix method with 'CRI','RCI','CMO',or'RMO'
ZINDEX	T = Use zero indexing or F = Use one indexing.

Value

A 'row bound" sparse matrix object with components"

nnz = the number of non-zero elements in ra.

nr = the number of rows in matrix A.

nc = the number of columns in matrix A.

ia = the row index.

ja = the column index.

ra = the non-zero coefficients in A

rnames = matrix row names – may be ”

cnames = matrix column names – may be ”

SMM = the sparse matrix type.

ZINDEX with T = Use zero indexing or F = Use one indexing.
