The numbers to sum are contained indatawhich is thenamed rangeC5:I13.
We can’t use a function likeSUMby itself, because SUM willaggregateresults and return a single value.
The purpose of BYROW is to process data in a “by row” fashion.
For example, if BYROW is given an array with 10 rows, BYROW will return singlearraywith 10 results.
This result is fully dynamic.
error, we use adouble negative(–) to force any empty cells to zero.
Next, we need to createarray2.
The first array contains 7 columns, so we need the second array to contain 7 rows.
BYROW can apply stock functions like SUM, COUNT, and AVERAGE or a custom LAMBDA function.
MMULT Function
The Excel MMULT function returns the matrix product of two arrays.
The result from MMULT is anarraythat contains the same number of rows asarray1and the same number of columns asarray2.
COLUMN Function
The Excel COLUMN function returns the column number for a reference.
For example, COLUMN(C5) returns 3, since C is the third column in the spreadsheet.
When no reference is provided, COLUMN returns the column number of the cell which contains the formula.
SEQUENCE Function
The Excel SEQUENCE function generates a list of sequential numbers in an array.
The array can be one dimensional, or two-dimensional, determined byrowsandcolumnsarguments.
