How to Use This Calculator
- Enter the elements of the first matrix in the ‘Matrix 1’ textarea, separated by spaces.
- Enter the elements of the second matrix in the ‘Matrix 2’ textarea, separated by spaces.
- Select the desired operation from the ‘Operation’ dropdown.
- Click the ‘Calculate’ button to perform the matrix operation and visualize the result.
Formula & Methodology
Matrix operations follow specific rules:
- Addition:
C[i][j] = A[i][j] + B[i][j] - Subtraction:
C[i][j] = A[i][j] - B[i][j] - Multiplication:
C[i][j] = ∑ A[i][k] * B[k][j]
