Hey, can someone explain, why the results are different? And which way is the right one? Thanks.
X=A+B+C-D;
Sum1=sum(X)
Sum2=sum(A)+sum(B)+sum(C)-sum(D)

SUM1 is the right one.
It calculates your resultant matrix’s sum
But the latter calculates the sum o each matrices and does the arithmetic operations but then also it depends on your wish.
