I have a matrix with two columns. The first column is numbers and the second is a string of words. I want to sort the entire matrix in ascending order based on the first column entries and without losing each number's second column pair. A simplified example is as follows:

Apple
Orange
Pear
Peach
to 
Peach
Orange
Apple
Pear

A MATLAB matrix cannot hold text. Is this a cell array?

Whoops, yes it is a cell array. Thanks!

在 MATLAB Online 中打开

C = {4, 'Apple';
     3, 'Orange';
     6, 'Pear';
     1, 'Peach'};
sortrows(C)
ans =
    4×2 cell array
      [1]    'Peach' 
      [3]    'Orange'
      [4]    'Apple' 
      [6]    'Pear'
