# Upper Triangular Matrix Calculator Online

### Explanation:

The Upper Triangular Matrix is the matrix which must be a square matrix having all the entries or elements below the main diagonal are zero.

### Properties of Upper Triangular Matrix

• The outcome of adding two upper triangular matrices is an upper triangular matrix.
• An upper triangular matrix is created by multiplying two upper triangles.
• The upper triangular matrix's inverse retains upper triangular.
• Lower triangular matrix is created by transposing the upper triangular matrix, UT = L.
• An upper triangular matrix retains its upper triangular shape if any scalar number is multiplied by it.

Upper Triangular Matrix Example:

A =
 1 3 5 7 0 9 8 3 0 0 2 4 0 0 0 2

Now in the above given matrix, the main diagonal elements are 1, 9, 2, 2 and the entries below the main diagonal are all zero which means the the matrix is Upper Triangular Matrix.
