Google Sheets MDETERM Function: Syntax, Examples & Tips

square_matrix:
The range of cells that represents a square matrix for which you want to calculate the determinant. The matrix must have the same number of rows and columns.

What is the MDETERM Function?

The MDETERM function in Google Sheets is a mathematical function used to calculate the determinant of a matrix. The determinant is a scalar value that can provide important information about the matrix, such as whether it is invertible. This function is particularly useful in linear algebra, engineering, and statistics.

In simpler terms, MDETERM allows you to find a specific value that summarizes certain properties of a matrix, which can be useful in various mathematical computations.

A Practical Example

Imagine you are working with a 2x2 matrix representing a system of equations:

Matrix:

You want to calculate the determinant of this matrix to determine if it is invertible.

MDETERM Formula

To achieve this, you would use the MDETERM function as follows:

=MDETERM(A1:B2)

In this formula:

• A1:B2 is the range that contains the matrix for which you want to calculate the determinant.

Result of the Formula

When you apply the MDETERM formula to the matrix, the output would be:

-10

This result indicates that the determinant of the matrix is -10, which means the matrix is invertible (since the determinant is not zero).

Why Use MDETERM?

MDETERM is beneficial because it simplifies the process of calculating the determinant of a matrix. It allows you to quickly assess the properties of matrices without having to perform manual calculations. This can be particularly useful in fields such as data analysis, engineering, and mathematical modeling.

Key Takeaways:
