MATRIX("LEHMER",order)


  • is the order of the Lehmer matrix.

Description

  • This function gives the lehmer matrix of order 3.
  • The the n×n Lehmer matrix, is the constant symmetric matrix defined by  
  • Also the inverse of a Lehmer matrix is a tridiagonal matrix and is known to be symmetric tridiagonal.
  • And the value of this matrix have strictly negative entries (i.e., with positive eigenvalues).
  • Example of 2x2 and 3x3 lehmer matrices are
