**MINVERSE Function in Excel**

**The MINVERSE** **function **in Excel is a built-in mathematical function that calculates the inverse of a matrix, allowing for effective solutions to complex equations and optimization problems.

**Syntax:**

`MINVERSE(array)`

**Arguments:**

ARGUMENT |
REQUIRED/OPTIONAL |
EXPLANATION |
---|---|---|

array |
Required | A square numeric array with rows and columns. |

**MINVERSE in Excel Not Working: Common Reasons with Solutions**

**Reason 1 – The Input Range Contains Blank Cells**

If any of the input ranges or cells contain blank cells or have no values, **the MINVERSE function **will return a **#VALUE** error.

**Solution – Ensure Valid Cell Data**

Ensure that all required cells have valid data for the function to work correctly.

**Reason 2 – Cell Contains Text Values Instead of Numbers **

If any of the cells in the input range contain text values instead of numbers, **the MINVERSE function **will return a** #VALUE** error.

**Solution – Avoid Text Values or Alphabets in Dataset**

A matrix with a text value in it can’t be used for mathematical operations.

**Reason 3 – Matrix Is Not Square**

In case the matrix is not square,** the MINVERSE function** will return a **#VALUE** error. Only square matrices can have an inverse.

**Solution – Maintain an Equal Number of Rows and Columns**

For** the MINVERSE function** to work properly, the matrix must be a square matrix, meaning it should have an equal number of rows and columns.

**Reason 4 – The Determinant of a Matrix is zero**

If the determinant is zero, it indicates that the matrix has no inverse, and the **MINVERSE **function will show **#NUM!** error.

**Solution – Ensure That the Matrix Is Invertible**

To use **the MINVERSE function** successfully, the matrix must be invertible, meaning it should have a non-zero determinant.

*NOTE:**Non-invertible matrices arise from interdependent variables, redundant data, or model inconsistencies. Understanding them is crucial for solving real-world problems involving linear systems and matrix operations.*

**Reason 5 – Lack of Space in the Output Range**

Ensure sufficient output space matching the matrix dimensions (e.g. 4×4 for a 4×4 original matrix) to avoid the **#SPILL! **error with **the MINVERSE function**.

**Solution – Provide Enough Space in the Output Range**

Make sure there is enough space in the output range for** the MINVERSE function **to work.

**How to Use the MINVERSE Function in Excel**

Consider a list of supply routes for a company. Calculating the inverse of the transportation cost matrix enables you to identify the most cost-effective supply routes.

The matrix is structured, with each row representing a supplier and each column representing a production facility. In our dataset, each number in the matrix represents the transportation cost (in dollars per unit) associated with sourcing raw materials from different suppliers. The value at position (i, j) represents the cost of transporting materials from supplier i to production facility j.

- Select cell
**C12**and then enter**the MINVERSE function**, using the array**C5:F8**. as the argument.

*NOTE: **If you have Microsoft Excel 365, enter the formula in the top-left cell of the output range and press Enter.*

*For previous Excel versions, first, select the entire output range, enter the formula in the top-left cell, and press Ctrl + Shift + Enter. Excel adds curly brackets to the formula.*

- The result will be displayed across the cell range
**C12:F15**.

- Negative and positive values in the inverse matrix represent less efficient and more efficient transportation routes, respectively. Analysts can use these values to identify cost-effective routes and optimize the supply chain.

**Frequently Asked Questions**

**How can I check if my matrix is square?**

To determine if your matrix is square, compare the number of rows and columns. If they are equal, your matrix meets one of the requirements for **the MINVERSE function**.

**Why does MINVERSE give inaccurate results?**

When working with **the MINVERSE function**, it’s important to be aware of the precision limitations in Excel. Keep in mind that Excel has a 16-digit precision limit, which means that large matrices or those requiring high levels of precision may lead to inaccurate results. Rounding errors or loss of precision can occur during the calculation process

**Can the Excel version impact the performance of MINVERSE?**

Yes. The performance of the** MINVERSE** function can be influenced by the version of Excel being used. In previous versions, a three-step process involving selecting the output range, entering the formula, and using the** CTRL+SHIFT+ENTER** shortcut was required. However, newer versions, such as Microsoft Excel 365, have simplified the process.

**How can I fix the MINVERSE function not working?**

To resolve **MINVERSE** issues, ensure correct formula syntax, use a square and compatible matrix, and handle error values or empty cells.

**I’m getting an error message when using MINVERSE. What does it mean?**

Error messages related to** MINVERSE** can indicate issues such as a non-invertible matrix, incompatible dimensions, or an incorrect formula structure.
