Question

由于我是初学者，你们这里真的很有帮助我使用matlab。现在我对matlab中的gui有所了解。我有个问题。我有一个gui和一个保存按钮的数字。我做了这个编码：

filename = inputdlg('Please enter the name for your figures');

extensions = {'fig','bmp'};

for k = 1:length(extensions

saveas(gcf, filename{:}, extensions{k})

set(gcf,'PaperPositionMode','auto')

end

但这只能保存在我gui的文件夹中。我想如何让用户可以选择他想在.bmg文件中保存gui的文件夹？

我使用此编码作为@gnovice建议的编辑：

filename = inputdlg('Please enter the name for your figures');

extensions = {'fig','bmp'};

directoryName = uigetdir;  %# Open directory-selection dialog

if directoryName == 0      %# User pressed the "Cancel" button...

  directoryName = '';      %#   ...so choose the empty string for the folder

end

saveas(gcf,fullfile(directoryName,fileName),extension);  %# Save to the folder

set(gcf,'PaperPositionMode','auto')

但是发生了这个错误：

??? Error while evaluating uipushtool ClickedCallback

??? Undefined function or variable 'fileName'.

Error in ==> fyp_editor>uipushtool9_ClickedCallback at 1605
saveas(gcf,fullfile(directoryName,fileName),extension);  %# Save to the folder

Error in ==> gui_mainfcn at 96
        feval(varargin{:});

Error in ==> fyp_editor at 42
    gui_mainfcn(gui_State, varargin{:});

Error in ==>
@(hObject,eventdata)fyp_editor('uipushtool9_ClickedCallback',hObject,eventdata,guidata(hObject))

您显然已经知道INPUTDLG对话框（因为您在上面使用它），所以我很惊讶您还没有遇到UIGETDIR对话框（或{{3} } 对于这个问题）。您可以使用它来让用户浏览并选择一个文件夹，如下所示：

fileName = inputdlg('Please enter the name for your figures');
directoryName = uigetdir('','Please select a folder to save to');
if directoryName == 0      %# User pressed the "Cancel" button...
  directoryName = '';      %#   ...so choose the empty string for the folder
end
filePath = fullfile(directoryName,fileName{1});  %# Create the file path
extensions = {'fig','bmp'};
for k = 1:length(extensions)
  saveas(gcf,filePath,extensions{k});  %# Save the file
  set(gcf,'PaperPositionMode','auto');
end

请注意，我使用函数any of the others来构建文件路径，该路径会自动处理您指定平台所需的FULLFILE。

用户如何将gui（结果）保存在其他文件夹中？
