Matrix computation Matrix Transpose : 轉置矩陣 Matrix Inverse : 反矩陣 Determinant Matrix calculation : 行列式值 Multiplication : 矩陣乘法 Systems of linear equation : 線性方程組

Matrix computation General system of linear equation : ax + by + cz = k 1 dx + ey + fz = k 2 gx + hy + iz = k 3 Solving Where linear equation by AX =b

Matrix computation 當 A 的反矩陣存在，則有唯一解 x , y, z 為 X = A-1 *b Thus,

Matrix computation For x x x example : + 2 y + 3 z = 2 + +z =3 + y -z =1

Matrix computation Solution: Show in online matrix calculator
