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();
)

Is uppercase used in a C program?
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.

What is the definition of Uper-triangular matrix?

What is strictly lower triangular 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.
The product of two upper triangular matrices is upper triangular?
yes it is

How do you set Matrix B on TI84?
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.)
What is a minor diagonal matrix?
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.
Are the upper ribs attached to the sacrum?
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.
What 3D shapes have triangular faces?
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 (Ξ), which has the shape of an equilateral triangle.
