结合数字矩阵和字符串数组 [英] Combining a matrix of numbers, with array of strings

问题描述

我正在尝试使用MatLAB以更巧妙的方式计算下面显示的代码:

I am trying to compute the code seen below, in a more clever way, using MatLAB:

f=zeros(5,2) %Values irrelevant.
y = {'A1', 'B1'; 
     f(1,1) f(1,2); 
     f(2,1) f(2,2); 
     f(3,1) f(3,2); 
     f(4,1) f(4,2); 
     f(5,1) f(5,2)};  

我得到的是f矩阵，在两个向量上方均带有A1和B1文本.

What I get out is the f matrix with the text of A1 and B1 above the two vectors.

对于更复杂的用途，我想有一种更简单的编写方法，但是我尝试了括号，方括号和花括号的任何组合，我想都可以使用..

I suppose there is a simpler way to write this, for more complex purposing, but I've tried any combination of parenthesis, brackets and curly brackets, num2str that I could think of.

有什么建议吗?

推荐答案

最简单的解决方案是使用 num2cell 并将结果与​​字符串连接:

The simplest solution is to use num2cell and concatenate the result with the strings:

y = [{'A1', 'B1'}; num2cell(f)];

示例

>> f = reshape(1:10, 2, [])';
>> y = [{'A1', 'B1'}; num2cell(f)]

y =
    'A1'    'B1'
    [ 1]    [ 2]
    [ 3]    [ 4]
    [ 5]    [ 6]
    [ 7]    [ 8]
    [ 9]    [10]
