MATRIX("CENTROSYMMETRIC",order)


  • is the order of the Centro symmetric matrix.

Description

  • This function gives the matrix of order 3 which is satisfying the property of centrosymmetric.
  • A centrosymmetric is the square matrix which is symmetric with its center.
  • An n × n matrix A = [ Ai,j ] is centrosymmetric when its entries satisfy

Failed to parse (syntax error): {\displaystyle A_{i,j} = A_{n−i+1,n−j+1} for 1 \le i,j \le n } .

  • All 2x2 centrosymmetric matrices have the form:
  • All 3×3 centrosymmetric matrices have the form:

  • Symmetric Toeplitz matrices are centrosymmetric.
  • Here MATRIX("centrosymmetric") gives centrosymmetric matrices of order 3.
  • Users can change the order of the matrix and the entries in calci.

Examples

  • MATRIX("centrosymmetric",3)
80 15 58
-88 -15 -88
58 15 80
  • MATRIX("centrosymmetric",4,9..15)
0 -3 5 0
0 5 -3 0
