A function indexing the columns of A

Description

A map from the joint space to an index set.

Usage

col_index(M, x)

Arguments

M	A vector of positive integers giving the alphabet sizes of the discrete variables.
x	An element of the joint space.

Value

A positive integer no greater than the cardinality of the joint space uniquely identifying x.

Examples

M=c(2,2,2)
col_index(M,c(1,1,1))
col_index(M,c(1,1,2))

M=c(4,3,2)
col_index(M,c(1,1,1))
col_index(M,c(2,1,1))
col_index(M,c(1,2,1))
col_index(M,c(1,1,2))
