This tool multiplies two matrices together to give you the resulting matrix.
How to Use the Matrix Multiplication Calculator
To use this calculator, enter the matrices A and B in the specified formats and click on the “Calculate” button.
- Matrix A: Enter the values of the matrix A separated by commas for each row and use a semicolon to separate the rows. For example, entering “1,2;3,4” will create a 2×2 matrix like this:
[ 1 2 ]
[ 3 4 ] - Matrix B: Enter the values of the matrix B in the same format as Matrix A. For example, entering “5,6;7,8” will create another 2×2 matrix:
- Click “Calculate” to get the resulting matrix of AxB in the result area.
How It Calculates the Results
The calculator parses the input strings into two-dimensional arrays (matrices). It then multiplies these matrices if their dimensions are compatible for matrix multiplication:
- Matrix A of dimensions (m x n) can only be multiplied by Matrix B of dimensions (n x p).
- The resulting Matrix C will have dimensions (m x p).
Each cell in the resulting matrix is calculated by taking the dot product of the corresponding row in Matrix A with the column in Matrix B.
Limitations
The calculator has a few limitations:
- It can handle only numerical values.
- Matrix dimensions must be compatible for multiplication. The number of columns in Matrix A must equal the number of rows in Matrix B.
- The input format must strictly follow the comma, semicolon-separated format as specified.
Use Cases for This Calculator
Calculating product of two matrices
You can easily calculate the product of two matrices by inputting the dimensions and elements of each matrix. The calculator will perform the multiplication for you and display the resulting matrix.
Handling matrices with different dimensions
If the two matrices have incompatible dimensions for multiplication, the calculator will prompt you with an error message and guide you on the correct dimensions needed for the operation. This feature ensures accurate matrix calculations every time.
Support for scalar multiplication
In addition to matrix multiplication, the calculator also supports scalar multiplication. You can enter a scalar value along with a matrix to perform scalar multiplication effortlessly.
