    Em đang có sơ đồ thuật toán xoắn ốc song song cách đều nhưng khi viết bằng matlab thì kết quả lại không đúng

    {
    int x[100],y[100];
    double deltaX,deltaY,Xmin,Ymin,Xmax,Ymax;
    deltaX=deltaY=0,1;
    Xmin=Ymin=-50;
    Xmax=Ymax=50;
    int n,m,i,d,p;
    x[0]=-50;
    y[0]=50;
    i=0;
    d=0;
    p=0;

    n==(Xmax-Ymin)/deltaX;
    m==(Ymax-Ymin)/deltaY;
    for(d=0;d<=n;d++)
    {
    for(i=0;i<=n;i++)
    {

    x[i]=x[i-1]+(-1)+pow((-1),p);
    y[i]=y[i-1];
    cout<<"X["<<i<<"]="<<x[i]<<endl;
    cout<<"Y["<<i<<"]="<<y[i]<<endl;
    }
    }
    cout<<n;
    system("pause");
    }

    Anh Ngohaibac ơi em đang dùng matlab để xử lí ảnh !em dùng ham "imread"để đọc một ảnh vậy ảnh đó phải được đặt ở folder nào của matlab ạ !hay chỉ cần ảnh đó có trong "my computer" của mình là được ạ ! em cảm ơn anh rất nhiều !
    có 2 cách:
    - bạn chỉ rõ đường dẫn của ảnh trong hàm imread
    -ở phía trên cửa sổ có mục current folder, bạn vào đó tìm đến đường dẫn của ảnh, rồi chạy hàm imread bình thường

Users of these applications typically download more information than they send. ADSL also allows simultaneous voice communication by transmitting data signals outside of the voice frequency range. Sometimes a faint hiss can be heard on the line. To eliminate the hiss, a voice/data splitter, commonly called a POTS splitter (Plain Old Telephone Service) is installed at the jack of each phone. The base transmission range for an ADSL line is 18,000 feet. ADSL can be extended to remote communities by using ADSL repeaters (to 48,000 feet) or fiber optic.
