Hello everyone
Can anyone help me with codes to calculate sum of numbers in the diagonal of a 2 dimensional matrix array. Please help. (a b c d e
f g h i j
j k l m n
o p q r s)

int[,] array = new int[2, 4] { { 1, 2, 3, 4 }, { 1, 2, 3, 4 } };
List<int> list = new List<int>();
for (int i = 0; i < array.GetLength(1); i++)
{
int sum = 0;
for (int j = 0; j < array.GetLength(0); j++)
{
sum += array[j, i];
}
list.Add(sum);
}
//list now has all sums of 2-d array!
//result is: 2,4,6 and 8

I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).
the function that I created to find the ...

Write a C program that should create a 10 element array of random integers (0 to 9). The program should total all of the numbers in the odd positions of the array and compare them with the total of the numbers in the even positions of the array and indicate ...

Hi. so this is actually a continuation from another question of mineHere but i was advised to start a new thread as the original question was already answered.
