This page is best for one clear job: quickly checking standard operations on small square matrices. For class exercises, introductory linear algebra, homework verification, and interview review, 2x2 and 3x3 cases already cover many of the matrices people handle by hand. You do not need a large symbolic system just to confirm a result.
The page is not trying to be a general-purpose computer algebra tool. It is a text-input calculator for small matrices, which is why it focuses on fast entry, clear operation choices, and immediate result checking instead of higher-dimensional or advanced matrix workflows.
The current page supports six operations.
The first three require both matrix A and matrix B. The last three require only matrix A.
現在のページは2x2と3x3の正方行列のみに対応しています。
加算・減算・乗算には行列Aと行列Bの両方が必要です。行列式・逆行列・転置は行列Aのみを使用します。
各行を1行ずつ入力し、値はスペースまたはカンマで区切ってください。行数と列数が選択したサイズと一致している必要があります。
行列式が0になる特異行列の場合、現在のページでは逆行列を求めることができません。
Add, subtract, multiply, transpose, invert, and evaluate determinants for 2x2 and 3x3 matrices.
