## Understanding the MMULT formula

Know the syntax and applications of the MMULT formula in Excel. It multiplies two matrices to get results that are useful. The syntax takes care of matrices of different sizes. The result reflects the mathematical calculation. Explore MMULT to understand the formula. See how it can be used.

### Syntax of the MMULT formula

To understand the manner to write MMULT formula, follow the syntax mentioned below.

| Syntax | |
|———————–|——————————-|
| =MMULT(array1, array2) | array1 and array2 are matrices |

MMULT formula in Excel is used to multiply two or more matrices, and it returns an output matrix. The two arrays/ matrices that are multiplied must have an equal number of columns and rows. The syntax of the MMULT formula consists of two array/matrix inputs that require dimensions compatible with each other, a row number which is calculated using multiplication of the last column of the first array with one less than the total number of rows present in the second array, followed by a column number equivalent to the total number of columns present in the second matrix.

In case some values are missing from any input or if the matrix’s size isn’t appropriate for this operation, #VALUE! will appear as an error message. Be mindful when using commas within brackets because Excel may inadvertently force elements into multiple arrays.

It can be used for various applications like stock forecast analysis, scientific researches, financial analysis, etc. As per Microsoft Support, it can take up-to 30 individual matrices as input arguments.

A source explains that MMULT is one of several key excel formulas used in data analysis (Ref: Investopedia).

Who needs a whole team when you have the MMULT formula? It’s the ultimate MVP of Excel.

### Applications of the MMULT formula

The MMULT formula is a versatile and useful tool in Excel. It can be utilized in various applications, ranging from financial analysis to scientific studies, making it a popular choice for professionals who need to manipulate and analyze large data sets.

A useful way to understand the applications of the MMULT formula is to examine practical examples. Consider the following table:

Column AColumn BColumn C
123
456
789

Using the MMULT formula with this data set can yield results such as multiplying each row by a specific value or calculating a dot product between two matrices. These calculations can be particularly helpful when working with complex data sets or creating visual representations of data.

It is worth noting that while the MMULT formula can greatly simplify complex data analysis tasks, it requires careful input formatting and manipulation for accurate results. Incorrect use of this formula may result in inaccuracies that adversely affect your work.

To ensure accurate results when using the MMULT formula, consider organizing your data carefully into appropriate formats for multiplication or visualization purposes. Additionally, double-checking formulas and input values before running calculations can prevent costly errors down the line.

## Examples of using the MMULT formula in Excel

To get the hang of MMULT in Excel, check out the “Examples of using the MMULT formula in Excel” section. It contains two sub-sections – Example 1: Multiply Matrices using MMULT formula and Example 2: Get the inverse matrix using MMULT formula. That’ll make solving this problem a breeze!

### Example 1: Multiplying Matrices using MMULT formula

Multiplying matrices can be done efficiently in Excel using the MMULT formula. Here’s how it works.

1. First, create two matrices in Excel by inputting the numbers in separate cells.
2. Select an empty cell where you want the product of the two matrices to be displayed.
3. Type in the MMULT formula, followed by the range or address of the first matrix, comma, and then the range or address of the second matrix enclosed in brackets.
4. Press enter and voila! The product of your two matrices will appear in the selected cell.

It’s as simple as that! Whether you’re working with small or large datasets, using MMULT is a quick and easy way to multiply matrices in Excel.

One thing to note is that the number of columns in the first matrix should match the number of rows in a second matrix for MMULT to work correctly. Otherwise, you’ll get an error message.

When dealing with complex calculations involving multiple matrices, it’s essential to have a good understanding of how they function and interact with each other. Using formulas such as MMULT can save time and simplify these operations.

As for the history behind multiplying matrices using Excel, it has been around since its early versions.
