Hey, i need help with school assignment, i have created an array of 8 rows and 20 columns whose elements are random numbers between 10 and 100:
i have to find the elements in A which are between 30 and 65! and Calculate the sum of these numbers.
this is what i got so far:
if A(i,j)>30 & A(i,j)<65
And this only shows the first if argument, and the sum is 401 which i think is the sum if hiw many numbers are greater than 30.
Now my teacher says we have to use this format which i dont understand why:

You had it!
if A(i,j)>30 && A(i,j)<65
B=B+A(i,j);%B is the sum of all elements of A between 30 and 65

No need to initiate two values s and N, only one for accumulator.
