proper

The polynomial matrix is column//row proper or not

Description

The program returns a logical value, whether the given polynomial matrix is column or row proper or both. A ‘proper’ matrix called in other way column or row ‘reduced’.

Usage

proper(pm,type=c("col","row","both"),print=c(TRUE,FALSE))

Arguments

`pm`	a `polyMatrix` class polynomial matrix
`type`	the type of rating `row`//`col`//`both`
`print`	the kind of printing

Details

The program calculates first the column or row associated matrices, and the answer depends on there ranks. A polynomial matrix is ‘proper’ if the associeted matrix has a full rank. The program has an invisible silent output.

Value

Logical: TRUE or FALSE. The associated matrix is only an optional part of the output, and the print.

Examples

pm <- polyMgen.d(2,2,rawData=ch2pn(c("-1+7*x","x","3-x+x^2","-1+x^2-3*x^3")))
pm
proper(pm) # the default is the col-property labeling
(proper(pm,print=FALSE)) # the invisible output, without printing
proper(pm,"col")
proper(pm,"row")
proper(pm,"both")

# clean up
# rm(pm)
