Question

昨天我使用了一些对我来说完美无缺的代码，今天我尝试使用它并且它没有像以前那样做同样的工作。我不确定为什么在再次运行之前我没有做任何改动代码是：

[FileName,PathName,FilterIndex] = uigetfile('*.txt*','MultiSelect','on');

numfiles = size(FileName,2);

for ii = 1:numfiles
    FileName{ii};

    entirefile =fullfile(PathName,FileName{ii});

    fid = fopen(entirefile);

    tline = fgets(fid);
    while ischar(tline)

        parts = textscan(tline, '%f;');

        if numel(parts{1}) > 0
            A = [ A ; parts{:}' ];
        end
        tline = fgets(fid);
    end

    fclose(fid);

end  

B = A(1:end)

昨天我使用它时，B = A(1:end)显示了我希望上传文件的所有数据，但现在它以二进制形式显示数据，例如：

[ 1x11 double]
[ 1x11 double]
[ 1x11 double]
[ 1x11 double]
[ 1x11 double]
[ 1x11 double]
[ 1x11 double]
[ 1x11 double]
[ 1x11 double]
[ 1x11 double]
[ 1x11 double]
[ 1x11 double]

循环有效，只能从文件中导入数字数据任何人都可以建议为什么会出现这种情况？或者如何从[ 1x11 double]获取数据？

Answer 1

我想我已经找到了你的问题。问题在于%f这一行：

parts = textscan(tline, '%f;');

如文档here所示，您只需提取双格式数据。将%f更改为%s，您应该感觉良好。

如何从双倍数据中获取数据？ MATLAB
