Create Minterm Matrices
This function creates minterm and implicant matrices. It is mainly used for internal and demonstration purposes.
mintermMatrix(noflevels, logical = FALSE)
noflevels |
The number of levels for each exogenous factor. |
logical |
Logical, return the matrix in logical values (only bivalent data). |
Minterm matrices contain all unique and complete conjunctions that can be formed from all levels of k factors (Dusa and Thiem 2015). The total number of minterms d is given by d = ∏_{j = 1}^{k}{p_{j}}, where p_{j} is the number of levels for exogenous factor j and k is the total number of exogenous factors. A minterm matrix is an essential part of a truth table.
