I've written the function for a 3x3 matrix. In 3x3 upper triangular matrix, there are 3 elements whose value is 0 (i < j).. So, when count is 3, program will display that matrix is upper triangular. You can modify the function as per your matrix size.
void upper() // Function for finding Upper Triangular Matrix
{
int count = 0;
printf("\nEnter a 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("\nThe Matrix is upper triangular\n");
else
printf("\nThe Matrix is not upper triangular\n");
}
int main() // Main Function
{
upper();
)

By convention, all upper-case is used to identify macros and single capitals to identify template parameters. However, programmers are free to use upper-case as they see fit.

Uper-triangular Matrix A square matrix A whose elements aij=0 for i>j is called upper triangular matrix.
write a programe to build a sparse matrix as an array. write function to check if the sparse matrix is a square, diagonal,lower triangular, upper triangular or tridiagonal matrix
A strictly lower triangular matrix is a kind of (lower) triangular matrix. Term "lower" implies matrix has elements only in the lower half. The condition "strictly" implies that even the "diagonal" of such lower triangular matrix is populated with '0's. The strictly lower triangular matrix thus has '0's in its diagonal as well as the upper triangle part. In other words, a strictly lower triangular matrix is a lower triangular matrix minus its diagonal.
yes it is

Press 2ND MATRIX (above x-1). Select EDIT at the top with the arrow keys. The select matrix [B] and press ENTER. You can now edit the matrix. (Use the numbers at the upper right to set the size.)
A minor diagonal matrix is one where the only non-zero entries are along the diagonal that runs from bottom most left to upper most right.
No, the upper ribs are attached to the thoracic vertebrae in the back, not to the sacrum. The sacrum is a triangular bone at the base of the spine that connects the spine to the hip bones.
In geometry, a deltahedron (plural deltahedra) is a polyhedron whose faces are all equilateral triangles. The name is taken from the Greek upper case delta (Δ), which has the shape of an equilateral triangle.
no it cant
It's bone shape. I don't know what to call it, but the upper part of the shaft is triangular and lower is a bit more cylindrical.
