grapes-times-grapes: Cross-Product of in-database objects.

In Fuzzy-Logix/AdapteR: Converts R syntax to SQL to provide fast analytics using in-database C++ library DB Lytix.

Description

%*% does the Cross-Product of in-database objects.

Usage

pObj1 %*% pObj2

Arguments

pObj1	can be an in-database object like FLMatrix,FLSparseMatrix,FLVector or a normal R object like matrix,sparseMatrix,vector
pObj2	can be an in-database object like FLMatrix,FLSparseMatrix,FLVector or a normal R object like matrix,sparseMatrix,vector

Details

The Cross-Product of in-database objects mimics the %*% of R data types. All combinations of operands are possible just like in R and the result is an in-database object.

Value

%*% returns an in-database object if there is atleast one in-database object as input.Otherwise, the default behavior of R is preserved

Examples

flmatrix <- FLMatrix("tblMatrixMulti", 5,"MATRIX_ID","ROW_ID","COL_ID","CELL_VAL")
Rvector <- 1:5
ResultFLmatrix <- flmatrix %*% Rvector
