Google Sheets

MMULT is a function in Google Sheets that allows you to multiply matrixes. To use it, you first need to create two arrays, or lists of numbers, one for the first matrix and one for the second. Then, you need to use the MMULT function to multiply the two arrays together. The result will be a new matrix, containing the products of the two original arrays.

The syntax of MMULT in Google Sheets is as follows: =MMULT(array1,array2) The MMULT function multiplies the arrays array1 and array2 and returns the product.

The MMULT function in Google Sheets allows you to multiply two arrays together. The function takes two arrays as input and returns the product of the arrays as a new array. The function is useful for multiplying large arrays together, as it can be faster than using the traditional multiplication operator (*).

For example, the following array contains the squared values of the first ten positive integers:

=MMULT(A1:A10,B1:B10)

This array will return the following result:

={1, 4, 9, 16, 25, 36, 49, 64, 81, 100}

There are a few instances when you should not use MMULT in Google Sheets. First, when you have a large number of data points, the function may not calculate correctly. Additionally, you should not use MMULT when you have data that is not linearly related. Finally, the function may not work if your data is located in different cells or sheets.

There are a few similar formulae to MMULT in Google Sheets. One is the PRODUCT function, which multiplies all the numbers in a given range. The VLOOKUP function can also be used to multiply two arrays of numbers. Finally, the TRANSPOSE function can be used to turn a column of numbers into a row, which can then be multiplied.
