Calculating euclidean distance in a matrix

Question

I am trying to calculate the euclidean distance in a matrix in C, I saw a similar post and tried it on my own matrix but as it is different I do not know how to make it work. This is my code:

#include <stdio.h>
#include <math.h>

int main()
{

    double distance[3][3] = {0};
    double myArray[3][9] = {{50, 10, 10, 20, 10, 0, 0, 0, 0},
                            {50, 0, 0, 0, 0, 20, 10, 15, 5},
                            {70, 10, 0, 10, 0, 0, 10, 0, 0}};

    int i;
    int j, k;
    for (i = 0; i < 3; i++)
    {
        for (j = 0; j < 9; j++)
        {
            double temp = 0.0f;

            for (k = 0; k < 9; k++)
            {
                temp += pow(myArray[i][k] - myArray[j][k], 2);
            }
            distance[i][j] = (int)sqrt(temp);
        }
    }
    for (i = 0; i < 3; i++)
    {
        for (j = 0; j < 3; j++)
        {

            printf("%f ", distance[i][j]);
            if (j == 2)
            {
                printf("\n");
            }
        }
    }
    return 0;
}

The result is close to being correct, but it displays like this:

0.000000 38.000000 28.000000 
38.000000 0.000000 35.000000 
28.000000 35.000000 0.000000

Any help is appreciated!
