8. Java Examples on Various Matrix Operations
Matrix is a rectangular arrangement of rows and columns. Triangular matrix is a kind of square matrix. A square matrix is called lower triangular if all the entries above the main diagonal are zero. A square matrix is called upper triangular if all the entries below the main diagonal are zero. Matrix that is both upper and lower triangular is called a diagonal matrix. Sparse matrix is a matrix in which most of the elements have a value of zero. This section contains Java programs to display transpose matrix, upper and lower triangular matrix, programs to find trace of a given matrix, add two m*n matrix from user input, performs matrix multiplication and checks whether given matrix is a sparse matrix or not.
