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

- 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.
