0.销售订单管理系统
0.1 功能:
- 打开文件
- 查询订单
- 插入订单
- 订单统计
- 系统退出
0.2 数据库:
- 数据文件Excel
0.3 字段:
- 编号(E111)

1.系统设计
1.1 查询订单页面
查询条件:订单编号
输出内容:客户姓名、金额
1.2 插入订单页面
输入内容:订单编号、客户姓名、金额
按钮内容:确定、重置、返回
1.3 订单统计页面
输出内容:订单总额、大写金额(元)、订单交易数(个)
按钮内容:查询、重置、返回
2.分析设计准备
2.1 如何实现系统功能
2.1.1 模块Module
- 组成系统的基本单元
- 由内部属性和外部属性组成
- 内部属性:算法(函数体)、内部变量(局部变量)
- 外部属性:功能(函数名)、输入输出数据(参数)
2.2 Matlab存取Excel文件数据
函数:
- xlsfinfo()
- [data, textdata] = xlsread(filename,sheet,range)
- [status,message] = xlswrite(filename,sheet,range)
2.3 Matlab Graphics User Interface
练习
- 向execl中写入文件,金额转换成大写。
-
完整代码第一部分:向execl中写入文件
页面如下(页面中的读取函数在第一部分的代码中未写):
Test.m:
关键代码:
% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
global num txt
[num,txt] = xlsread('YH.xlsx');
numy = get(handles.edit1,'string');
num2 = {numy};
namey = get(handles.edit2,'string');
name2 = {namey};
money = get(handles.edit3,'string');
% money2 = {money};
money2 = str2num(money);
len = size(txt,1)+1;
range = num2str(len);
if isempty(numy)==1
msgbox('订单编号为空,请重新输入');
end
if isempty(namey)==1
msgbox('客户姓名为空,请重新输入');
end
if isempty(money)==1
msgbox('金额为空,请重新输入');
end

xlswrite('YH.xlsx',name2,'sheet1',['A',range]);
xlswrite('YH.xlsx',money2,'sheet1',['C',range]);
msgbox('插入成功');
end
完整代码(冗长可略过):
function varargout = Test(varargin)
% TEST MATLAB code for Test.fig
% TEST, by itself, creates a new TEST or raises the existing
% singleton*.
%
% H = TEST returns the handle to a new TEST or the handle to
% the existing singleton*.
%
% TEST('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in TEST.M with the given input arguments.
%
% TEST('Property','Value',...) creates a new TEST or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Test_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Test_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
