# How to generate an MMULT formula using AI.

To obtain information on the ARRAY_CONSTRAIN formula, you could ask the AI chatbot the following question: “To get the MMULT formula from an AI chatbot without prior knowledge of it, you could ask: 1. "How can I multiply two matrices in Excel?" 2. "Is there a formula in Excel to perform matrix multiplication?" 3. "What Excel function can I use to multiply arrays?" 4. "Is there a way to calculate the product of two matrices in Excel?" 5. "What formula should I use to multiply two ranges of cells in Excel?" By asking any of these questions, the AI chatbot should be able to provide you with the MMULT formula as a solution.”

## MMULT formula syntax

The MMULT function in Excel is used to multiply two matrices together. The syntax for MMULT is: MMULT(array1, array2) - array1: This is the first matrix or range of cells that you want to multiply. - array2: This is the second matrix or range of cells that you want to multiply. Both array1 and array2 must have the same number of columns in order for the multiplication to be valid. The resulting matrix will have the same number of rows as array1 and the same number of columns as array2. Remember to enter the MMULT formula as an array formula by pressing Ctrl+Shift+Enter after typing it, since it returns an array of values.

## Use Cases & Examples

In these use cases, we use the MMULT formula to perform matrix multiplication and calculate the resulting matrix. The MMULT formula takes two or more matrices as input and returns the product of those matrices.
