Why I'm getting AAAA... when using char??

So i got a list of names in an excel file, transfer them to a cell within their z-values assossiated

I want to sort the names from the least to the high z-value so what I'm doing is:

cell=char(info);

coded_names=double(info);

sorted_names=sortrows(coded_names); % as a first row of the matrix I have the z-values

Now I have everything sorted just translate the numeric code that matlab has to letters again BUT

When I do:

list=char(sorted_names);

I get a list with AAAAAA for all the names

Can someone please explain me why? I did it before and it was working

Thanks!

Marc - can you provide a small example for your info object that demonstrates the problem? Note that the line

 cell=char(info);

seems incorrect as you are converting all data within info to characters and then calling this cell. Note that cell is a built-in MATLAB function (see cell) to create a cell array...it is never a good idea to name a variable in this manner.

@Marc: The code looks confusing. "cell=char(info)" redefines the command "cell" with a variable, which is not a cell, but a char matrix. Phew. And in the next step you convert it to doubles.

What about:

sort(info)

without any conversions?

Not sure what you're doing or what you want, but this sorts a cell array alphabetically:

words = strsplit('I want to sort the names from the least to the high')
sortedWords = sort(words)

You get:

words =
  1×12 cell array
    'I'    'want'    'to'    'sort'    'the'    'names'    'from'    'the'    'least'    'to'    'the'    'high'
sortedWords =
  1×12 cell array
    'I'    'from'    'high'    'least'    'names'    'sort'    'the'    'the'    'the'    'to'    'to'    'want'
