A matrix method for principal normal form of propositional formula is derived from disjunctive normal form and conjunctive normal form based on the extension principle and deletion principle of superscript vectors of simplified phrase and simplified clause. Calculation process of principal normal form with equivalent calculus or truth table is simplified by the method presented.
