Program Invers dan Determinan Matriks...

program determinan_invers_matriks;
uses wincrt;
var a,b,c,d,i,invers,p,q,r,s:real;
jawab:char;
pass:string[8];
begin
clrscr;
gotoxy(20,1);
writeln('Mencari Invers Matriks Ordo 2x2 ');
gotoxy(10,5);write('a=');read(a);
gotoxy(18,5);write('b=');read(b);
gotoxy(10,7);write('c=');read(c);
gotoxy(18,7);write('d=');read(d);
i:=(a*d)-(b*c);
if not(i=0) then
begin
invers:=1/((a*d)-(b*c));
p:=d*invers;
q:=-b*invers;
r:=-c*invers;
s:=a*invers;
writeln;
writeln ('Determinan matriks A ='); write (i);
gotoxy(25,10);writeln('Invers matriks A =');
gotoxy(10,13);write(p:0:3);
gotoxy(18,13);write(q:0:3);
gotoxy(10,16);write(r:0:3);
gotoxy(18,16);write(s:0:3);
end
else
begin
gotoxy(25,15);
writeln('Tidak ada invers matriks');
end;
end.

kalau program tersebut ditulis di TPW seperti berikut.

 

setelah itu pilih 'Run' atau ketik Ctrl + F9, maka akan diperoleh hasil sebagai berikut.

 

Selamat Mencoba !!!!
