Selanjutnya saya akan menampilkan program menu matriks sama seperti program sebelumnya, hanya saja untuk isi menu diubah menjadi untuk perkalian, determinan dan transpose matriks. Untuk Codingnya :
usescrt;
type t=object
m1,m2 : array [1..2,1..2] of integer;
lok : array [1..4] of integer;
procedure input;
proceduretampil;
procedure kali;
proceduredeterminan;
procedure transpose;
end;
var m : t;
i,j,k,pil,b,c : integer;
proceduret.input;
begin
clrscr;
writeln ('-----input matrik-----');
for i:= 1 to 2 do
begin
for j:=1 to 2 do
begin
write ('elemenmatrik [',i,',',j,']: ');
readln (m1[i,j]);
end;
end;
gotoxy (35,1); writeln('-------input matrik
II------');
k:=2;
fori := 1 to 2 do
begin
for j:= 1 to 2 do
begin
gotoxy(35,k);
inc (k);
write('elemenmatrik [',i,',',j,']: ');
readln(m2[i,j]);
end;
end;

Tampilan menu yang akan dihasilkan seperti di bawah ini :
Untuk pilihan pertama gunanya untuk membuat matriks dengan menginput angka angka elemen matriks yang kita inginkan :
Pilihan Kedua gunannya untuk menghasilkan proses perkalian dari matriks yang kita input.
Dan pilihan yang ketiga berguna untuk melalukakn proses determinannya.
Pilihan Keempat yaitu untuk mentranspose matriks
