Formula Used in “Matrix by Scalar Calculator”
The Matrix by Scalar Calculator is designed to facilitate the process of scalar multiplication of a matrix. The standard formula used in this calculation is:
M’ = k * M
Where:
- M’ = the resulting matrix after scalar multiplication
- k = the scalar value
- M = the original matrix
Step-by-Step Breakdown of the Formula
To understand the process of matrix multiplication by a scalar, let’s define each variable in the formula:
- M: This is the original matrix that contains multiple elements arranged in rows and columns.
- k: A scalar is a single number that is used to multiply each element of the matrix.
- M’: This is the new matrix generated after multiplying each element of the original matrix by the scalar.
Calculation Process
Here’s a step-by-step guide to perform matrix by scalar multiplication:
- Identify the original matrix (M) that you want to multiply.
- Determine the scalar value (k) that you will multiply by.
- Multiply each element in the matrix (M) by the scalar (k).
- The resultant matrix (M’) is the output of the calculation.
Example Calculation
Let’s illustrate this with a real-world example:
Consider the following matrix:
| Row | Column 1 | Column 2 |
|---|---|---|
| 1 | 2 | 3 |
| 2 | 4 | 6 |
We will multiply this original matrix (M) by a scalar value of 3 (k).
Inputs and Outputs Table
| Input Matrix (M) | Scalar (k) | Resulting Matrix (M’) | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|
|
3 |
|
In this case, we multiplied:
- 2 * 3 = 6
- 3 * 3 = 9
- 4 * 3 = 12
- 6 * 3 = 18
The resultant matrix after the scalar multiplication is:
| Column 1 | Column 2 |
|---|---|
| 6 | 9 |
| 12 | 18 |
This example demonstrates how the Matrix by Scalar Calculator works, providing an easy method to perform scalar multiplication with any matrix.
