Invers matriks berordo 2 dapat langsung diperoleh dengan cara: Tukar elemen-elemen pada diagonal utamanya.2 Computing the Inverse Matrix ¶ permalink. Sebaliknya, jika A matriks singular (det A = 0) maka matriks ini tidak memiliki invers. Dari hasil di atas, dapat kita simpulkan bahwa pasangan matriks yang saling invers adalah matriks A dan C. As a result you will get the inverse calculated Theorem: If A is invertible, then S is invertible if and only if the Schur complement D − CA−1B is invertible. If the left side of the row reduced echelon is not an identity matrix, the inverse does not exist. So the determinant is minus 2, so this is invertible.
