Thread: matrix with static method

Calculating identity matrix with static method in C

I wanted to make a static method for calculating the identity matrix of the order n in the C. how can I build this identity matrix using the static method. I know to create an identity matrix using simple methods. Any idea would be highly appreciated.

1) For creating a matrix in c its very simple either you can use the in built C functions or you can just use the code which I have given below:

class Matrix
{
float matrix [rows][columns];

}

This code will create a matrix of the order rows X columns which you will indicate
FYI rows=number of rows you would like in your matrix
columns=number of columns you would like in your matrix

2) Try the following code shown below which is resolving your problem.

void matrix()
{
int count = 0;
printf("\Insert the matrix ");
for(i = 0; i <= 2; i++)
for(j = 0; j <= 2; j++)
scanf("%d", &a[i][j]);

for(i = 0; i <= 2; i++)
{
for(j = 0; j <= 2; j++)
{
if(i <= j)
{
if(a[i][j] == 0)
count++;
}
}
}
if(count == 3)
printf("This is upper triangular Matrix\n");
else
printf("This is not an upper triangular Matrix\n");
}

int main()
{
matrix();
}
