Returns the sum of the squares of all elements of two matrices.


SUMX2PY2(x; y)

x and y are arrays or ranges of the same size. SUMX2PY2 calculates Calc sumx2py2 equation.png for the i elements in the arrays or ranges.
Advanced topic:
SUMX2PY2 evaluates its parameters x and y as array formulas but does not need to be entered as an array formula. In other words, it can be entered with the  ↵ Enter  key, rather than  Cntrl  +  ⇧ Shift  +  ↵ Enter . See the example below.


SUMX2PY2(A1:A2; {2|1})

where cells A1 and A2 contain 4 and 3 respectively, returns (42+22) + (32+12) = 30.

Advanced topic (parameter evaluated as array formula):

SUMX2PY2(A1:A2+1; {2|1})

when entered 'normally' (not as an array formula), and where cells A1 and A2 contain 3 and 2 respectively, returns ((3+1)2+22) + ((2+1)2+12) = 30. SUMX2PY2 forces (A1:A2+1) to be evaluated as an array formula (internally returning the array {4|3}).
