mình cũng sắp hoàn tất, nhưng 1 vấn đề mình ko biết làm đó là nút( Chấm Công), mình ko biết làm sao, xin các bạn chỉ giúp mình nha, mail minh là: nhattrung21@yahoo.com
function varargout = trunglam(varargin)
% TRUNGLAM M-file for trunglam.fig
% TRUNGLAM, by itself, creates a new TRUNGLAM or raises the existing
% singleton*.
%
% H = TRUNGLAM returns the handle to a new TRUNGLAM or the handle to
% the existing singleton*.
%
% TRUNGLAM(‘CALLBACK’,hObject,eventData,handles,…) calls the local
% function named CALLBACK in TRUNGLAM.M with the given input arguments.
%
% TRUNGLAM(‘Property’,'Value’,…) creates a new TRUNGLAM or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before trunglam_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to trunglam_OpeningFcn via varargin.

Em chào anh Bắc.
Hiện nay em đang lập trình GUI để thuyết trình cho đề tài nghiên cứu khoa học nhưng còn vướng 1 chút. A có thể giúp e một tẹo được không ạ…hihi
Em đang làm đề tài về OFDM, khi truyền file sound và file image thì hiển thị lên axes được, nhưng khi truyền file text thì em không biết làm thế nào để hiển thị kết quả lên cả ? axes nó có hỗ trợ hiển thị txt ko anh. a giúp em với…
thank a nhìu…
