pMmult

Multiplication of two polyMatrix class polynomial matrices

Description

Matrix multipliction for polyMatrix class polynomial matrices. Multiplies the two matrices only if they are conformable.

Usage

left %X% right

Arguments

`left`	a `polyMatrix` class object, scalar number or polynomial
`right`	a `polyMatrix` class object, scalar number or polynomial

Details

The number of columns in left must be equal to number of rows in right.

Value

A polyMatrix class object which is the product of the polyMatrix class left and right matrices.

Examples

pm <- polyMgen.a()
pm * t(pm)

# two constante matrices
a <- matrix(1:12,3,4)
b <- matrix(1:20,4,5)
a %*% b

a <- M2pM(a)
b <- M2pM(b)
a * b
a %X% b

pM2M(a) %*% pM2M(b)

# clean up
# rm(pm, a, b)
