Algoritma n program menentukan Matriks Simetri atau tidak

1.      Deklarasi

Baris, kolom, i, j           : int

Matriks             : string

Dekripsi

Read baris, kolom

  for  i ß 0 to baris do

     for j ß 0 to kolom do

            read matriks[i][j];

  end for

     end for         

          

  if (baris==kolom) {

    if (baris=2) { (matriks[0][1]==matriks[1][0])  write “Simetri”}

    else (baris =3) { (matriks[0][1]==matriks[1][0]) && (matriks[0][2]==matriks[2][0]) && (matriks[1][2]==matriks[2][1])} } write “Simetri”

else write “tidak simetri”

 end if

   end if
