MATRIX("TRIDIAGONAL",order)
- is the size of the Tridiagonal matrix.
Description
- This function returns the matrix with the property of tridiagonal.
- A square matrix with nonzero elements only on the diagonal and slots horizontally or vertically adjacent the diagonal.
- i.e., along the subdiagonal and superdiagonal.
- So a tridiagonal matrix is a matrix that has nonzero elements only on the main diagonal, the first diagonal below this, and the first diagonal above the main diagonal.
- A tridiagonal is of the form:
- A general tridiagonal matrix is not necessarily symmetric or Hermitian,but tridiagonal matrix is a matrix that is both upper and lower Hessenberg matrix.
- In Calci, MATRIX("tridiagonal") gives the tridiagonal matirx of order 3.
- Users can change the order of the matrix.
