You should enter a multi-cell array formula in a range of cells of the same size as the resulting array returned by the formula. If your Excel array formula produces an array larger than the selected range, the excess values won't appear on the worksheet. If an array returned by the fo...
it becomes an array formula that can execute multiple rows at a time. This shortcut works for vertical and multi-dimensional arrays. It is very effective for division, multiplication and matrix calculations.
In addition to the logical AND operation using multiplication shown above, other logical operations can be performed arithmetically. A logical OR operation can be accomplished with addition. For example, =SUM(IF(((A2:A10="Fax")+(B2:B10="Jones"))>0,1,0)) will count the number of ...
To add the total sales amount of 3 items when the quantities sold are 10, 20, and 30 and the sale prices are $3, $4, and $5 respectively, the SUMPRODUCT formula stores each multiplication product in an Array (Array size is 3) and then adds the three values from the Array. The SUM...

and allowing the calculation to broadcast the vector over the array. Similarly multiplication by a factor of 1000 would be applied to every element of the array. The table that implements this is shown in blue. Whether it is correct or not depends upon my understa...
Excel includes these functions for working with matrices: MMULT(A, B) for matrix multiplication AB MINVERSE(A) for finding an inverse A−1 MDETERM for finding the determinant We will examine these functions in this exercise and make practical use of them in the next. For our example of an...
