Java Program to display the upper triangular matrix
In this program, we need to display the upper triangular matrix.
Upper Triangular Matrix
Upper triangular matrix is a square matrix in which all the elements below the principle diagonal are zero. To find the upper triangular matrix, a matrix needs to be a square matrix that is, the number of rows and columns in the matrix need to be equal. Dimensions of a typical square matrix can be represented by n x n.
Consider the above example, principle diagonal element of given matrix is (1, 6, 6). All the elements below diagonal needs to be zero to convert it into an upper triangular matrix, in our example, those elements are at positions (2, 1), (3, 1) and (3, 2). To convert given matrix into the upper triangular matrix, loop through the matrix and set the values of the element to zero where row number is greater than column number.
Upper triangular matrix: 1 2 3 0 6 4 0 0 0
