      • em hỏi về so sánh trong matlab như sau:

        syms x real
        f1=log10(x);
        a=subs(f1,x,3);
        b=double(limit(f1,x,3,'right'));

        Khi thực hiện phép toán a-b thì kết quả không bằng 0, tức ở đây matlab coi 2 số a & b là khác nhau. Nhưng ta dễ dàng thấy rằng a = b = log3.. Mong chủ topic trả lời em vấn đề này nhé!

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.

                              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
