Description

Sum of squares function. SUMSQ(range) computes the sum of the squares of the values of the spreadsheet cells in the specified range.

The argument range can be a list of numbers, cell addresses, cell ranges (such as A1:A10).

Range can also be a matrix. In that case the function returns a matrix with one row and the same number of columns, with each element the SUMSQ of the corresponding column. If range is a row matrix, it is converted to a column matrix first.

The formula for SUMSQ is:

$$ \sum{}{}{x_i^2}$$
