    MatLab help needed

    Hi
    Please, help me with this one:
    Program Eyler;
    Uses
    Crt;
    Const
    H=0.1;
    Var
    X,y:array[0..100] of real;
    I:integer;
    Function f(x,y:real):real;
    Begin
    F:=0.218*(x*x+sin(1.6*x)+0.718*y);
    End;
    Begin
    Clrscr;
    For i:=0 to 9 do
    Begin
    X[0]:=0.2; y[0]:=1.2;
    X[i+1]:=x[i]+h;
    Y[i+1]:=y[i]+f(x[i],y[i])*h; {Eiler's formula}
    Writeln (x[,I,]=, x[i]:3:2);
    Writeln (y[,I,]=, y[i]:3:2);
    End;
    Readln;
    End.

    Results
    Х[0]=0.20 y[0]=1.20
    Х[1]=0.30 y[1]=1.29

    I've been looking for some instant MatLab sections on MathsNinja and MathsGurus, Perhaps, any ideas on the process. I know that it will take perhaps several pages to write down in detail.
