Matlab打印垫 [英] Matlab printmat

问题描述

我是Matlab的新手.有没有办法使用printmat打印2个单词的标题?

I am new to Matlab. Is there a way to use printmat to print 2 words heading?

示例结果如下:

 Title One        Title Two         Title Three
        11               22                  33
        22               33                  44

这是我当前尝试修改的代码:

Here is the code i currently trying to modify:

matA = [ 11 22 33; 22 33 44];
printmat(matA, '' , '' , 'TitleOne TitleTwo TitleThree');

我似乎无法在标题"和一个"之间添加空格，其中添加空格始终会导致以下结果:

I can't seems to add a space in between 'Title' and 'One' where adding the space always result in the following outcome:

printmat(matA, '' , '' , 'Title One Title Two Title Three');

     Title              One               Title
        11               22                  33
        22               33                  44

感谢您的帮助.

推荐答案

根据Matlabs的帮助，printmat将不会提供您要查找的内容.您可以改用sprintf.

According to Matlabs help, printmat will not provide what you are seeking. You can use sprintf instead.

a = [ 11 22 33; 22 33 44];
s = {'Title One' 'Title Two' 'Title Three'};
s1 = sprintf('%12s\t%12s\t%12s\t\n', s{:});
s2 = sprintf('%12d\t%12d\t%12d\n', a);

horzcat(s1,s2)

这导致

ans =

   Title One       Title Two     Title Three    
          11              22              22
          33              33              44

如果最好使用printmat(例如，因为它更灵活)，则可以使用evalc和strrep解决.这里的技巧是在调用printmat时用其他符号(例如问号)替换空格，通过evalc将输出存储在字符串中，然后使用strrep用空格替换问号.作为一个很好的副产品，您可以将表作为字符串...

~edit~
If the use of printmat is preferable (e.g., because it is more flexible) you can work around by using evalc and strrep. The trick here is to replace the spaces with other symbols (e.g. question marks) in the call to printmat, store the output in a string via evalc, and then use strrep to replace the question marks by spaces. As a nice byproduct, you get the table as a string...

a = [ 11 22 33; 22 33 44];
x = evalc('printmat(matA, '''' , ''a b c'' , ''Title?One Title?Two Title?Three'')');

s = strrep(x, '?', ' ')

这将导致

s =


                 Title One    Title Two  Title Three
            a     11.00000     22.00000     33.00000
            b     22.00000     33.00000     44.00000

但是，printmat和evalc的组合会引起很多撇号...

However, the combination of printmat and evalc causes a lot of apostrophes...
