## Ruby program to calculate the sum of matrix elements

```
# Ruby program to calculate the sum
# of matrix elements
TwoDArr = Array.new(2){Array.new(2)}
sum = 0;
printf "Enter elements of MATRIX:\n";
i = 0;
while (i < 2)
j = 0;
while (j < 2)
printf "ELEMENT [%d][%d]: ", i, j;
TwoDArr[i][j] = gets.chomp.to_i;
j = j + 1;
end
i = i + 1;
end
printf "MATRIX:\n";
i = 0;
while (i < 2)
j = 0;
while (j < 2)
sum = sum +TwoDArr[i][j];
print TwoDArr[i][j]," ";
j = j + 1;
end
i = i + 1;
print "\n";
end
printf "Sum of matrix elements: %d\n",sum;
```

```
Enter elements of MATRIX:
ELEMENT [0][0]: 1
ELEMENT [0][1]: 2
ELEMENT [1][0]: 3
ELEMENT [1][1]: 4
MATRIX:
1 2
3 4
Sum of matrix elements: 10
```
