Examples

### numeric Kronecker product 
c(1,2) %kronecker% c(2,3)
#> [1] 2 3 4 6

### symbolic Kronecker product 
array(1:4, dim = c(2,2)) %kronecker% c("a","b")
#>      [,1]      [,2]     
#> [1,] "1 * (a)" "3 * (a)"
#> [2,] "1 * (b)" "3 * (b)"
#> [3,] "2 * (a)" "4 * (a)"
#> [4,] "2 * (b)" "4 * (b)"
