Arrange all combinations of rows of two matrices

Given X and Y, both matrices where the rows are counts of multinomial trials, produce all combinations rowwise, concatenate the rows into a new matrix, and calculate the log multinomial coefficients for the combination.

Usage

combinate(X, Y)

Arguments

X

Matrix 1

Y

Matrix 2

Value

A list containing Sspace, the sample space (vectors of counts), and logC, a vector of the log multinomial coefficients.

Examples

slist_2_3 <- combinate(matrix(sspace_multinom(2, 5), ncol = 2, byrow = TRUE),
   matrix(sspace_multinom(3, 6), ncol = 3, byrow = TRUE))
