Understanding Matrix Operations
Here is a detailed explanation of each matrix operation available in our calculator:
Matrix Addition
Matrix addition is performed element-wise. Two matrices can be added if they have the same dimensions. The sum of two matrices \( A \) and \( B \) is a matrix \( C \) where each element \( c_{ij} \) is the sum of elements \( a_{ij} \) and \( b_{ij} \).
For example, consider the matrices:
\[ A = \begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix}, \quad B = \begin{bmatrix} 5 & 6 \\ 7 & 8 \end{bmatrix} \]Their sum \( C = A + B \) is:
\[ C = \begin{bmatrix} 1+5 & 2+6 \\ 3+7 & 4+8 \end{bmatrix} = \begin{bmatrix} 6 & 8 \\ 10 & 12 \end{bmatrix} \]Matrix Subtraction
Matrix subtraction is performed element-wise. Two matrices can be subtracted if they have the same dimensions. The difference of two matrices \( A \) and \( B \) is a matrix \( C \) where each element \( c_{ij} \) is the difference between elements \( a_{ij} \) and \( b_{ij} \).
For example, consider the matrices:
\[ A = \begin{bmatrix} 5 & 6 \\ 7 & 8 \end{bmatrix}, \quad B = \begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix} \]Their difference \( C = A – B \) is:
\[ C = \begin{bmatrix} 5-1 & 6-2 \\ 7-3 & 8-4 \end{bmatrix} = \begin{bmatrix} 4 & 4 \\ 4 & 4 \end{bmatrix} \]Matrix Multiplication
Matrix multiplication is performed by taking the dot product of rows of the first matrix with columns of the second matrix. Two matrices \( A \) and \( B \) can be multiplied if the number of columns in \( A \) is equal to the number of rows in \( B \). The resulting matrix \( C \) will have dimensions equal to the number of rows in \( A \) and the number of columns in \( B \).
For example, consider the matrices:
\[ A = \begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix}, \quad B = \begin{bmatrix} 5 & 6 \\ 7 & 8 \end{bmatrix} \]Their product \( C = A \times B \) is:
\[ C = \begin{bmatrix} 1\cdot5 + 2\cdot7 & 1\cdot6 + 2\cdot8 \\ 3\cdot5 + 4\cdot7 & 3\cdot6 + 4\cdot8 \end{bmatrix} = \begin{bmatrix} 19 & 22 \\ 43 & 50 \end{bmatrix} \]Matrix Inversion
Matrix inversion is the process of finding the inverse of a square matrix, if it exists. A matrix \( A \) is invertible if its determinant is non-zero. The inverse of \( A \) is denoted as \( A^{-1} \) and satisfies the equation \( A \cdot A^{-1} = I \), where \( I \) is the identity matrix.
For example, consider the matrix:
\[ A = \begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix} \]The determinant of \( A \) is:
\[ \text{det}(A) = 1\cdot4 – 2\cdot3 = 4 – 6 = -2 \]The inverse of \( A \) is:
\[ A^{-1} = \frac{1}{\text{det}(A)} \begin{bmatrix} 4 & -2 \\ -3 & 1 \end{bmatrix} = \frac{1}{-2} \begin{bmatrix} 4 & -2 \\ -3 & 1 \end{bmatrix} = \begin{bmatrix} -2 & 1 \\ 1.5 & -0.5 \end{bmatrix} \]How to Use the Matrix Calculator
