MMULT calculates the array product of two arrays.

## Syntax

The number of columns for the first array must match the
number of rows for the second array. The square array has an equal
number of rows and columns.

MMULT (`array`,`array`)

`array` as the first argument represents the
first array with a specific number of columns.
`array` as the second argument represents the
second array with the number of rows the same as the number of columns
in the first array.

## Example

Choose the MMULT function. Select
the first array, add a comma after the range values that are added
to the formula, and then select the second array. Press Enter. The
output array will appear in the first selected range.
