Remove accent from struct

I have this info_circuitos.Name_circuito. I need to shearch in a name. but the struct have accents. a e i o u OR A E I O U. Could have accent in any of that letter.

I want to create a new info_circuitos.Name_circuito without accent Help pls.

Thanks

[sixwwwwww]

how many structs you have?

[5mid]

It can be of any size.

         Mónaco       
       Alemanha    Could be like that
      Austrália 
        Monreal      
        Espanha
         Itália

[sixwwwwww]

you can do it like this:

names = {files.name};
str = {'Á', 'É', 'Í', 'Ó', 'Ú', 'á', 'é', 'í', 'ó', 'ú'};
strreplace = {'A', 'E', 'I', 'O', 'U', 'a', 'e', 'i', 'o', 'u'};
for j = 1:length(names)
    for i = 1:numel(str)
        names{j} = regexprep(names{j}, str{i}, strreplace{i});
    end
end

Good luck!

I will try. I have already

nome = input('\nIntroduza o nome do circuito a remover: ','s');

    indice_nome = strfind(lower({info_circuitos.Nome_circuito}), lower(nome));

I will try.

Thanks

But if I search for mona it finds Mónaco?

[sixwwwwww]

you are welcome. if you want to avoid the loop then you can use the following method as well:

names = {files.name};
str = '[aeiou]';
startIndex = regexp(names,str);

It will find whether a vowel exist in names and return its starting index

[5mid]

It will change for example in Austrália the 'á' for a?

I don´t understand how this does that.

[5mid]

I think I don´t want that. I want like

            chars_old = 'ÁÉÍÓÚáéíóú'; 

            chars_new = 'AEIOUaeiou';

            str = info.Nome_circuito;

            [tf,loc] = ismember(str, chars_old);

            str(tf) = chars_new( loc(tf) );

But to change the structure.

[sixwwwwww]

I just tried the following code:

names = 'Austrália';
str = '[aeiou]';
startIndex = regexp(names,str);

and it is giving me result:

[2, 8, 9] for u, i and a

It shows that MATLAB is not finding á as a.

[5mid]

But this don´t change my struct. I think i´m not understanding what you are trying to say to me. This is my struct info.names

        Mónaco  

       Alemanha    
      Austrália 
        Monreal      
        Espanha
         Itália

I want it like

        Monaco       
       Alemanha    
      Australia 
        Monreal      
        Espanha
         Italia

[sixwwwwww]

you can do it as follow:

names = {files.name};
str = {'Á', 'É', 'Í', 'Ó', 'Ú', 'á', 'é', 'í', 'ó', 'ú'};
strreplace = {'A', 'E', 'I', 'O', 'U', 'a', 'e', 'i', 'o', 'u'};
for j = 1:length(names)
    for i = 1:numel(str)
        names{j} = regexprep(names{j}, str{i}, strreplace{i});
    end
end

I hope it solves your problem.

[5mid]

Man you´re god!!

Thanks, thats what I want.

I can´t choose you answer

[sixwwwwww]

you are welcome and why you can't choose my answer?

[5mid]

forget... The corret option is not the first.

[sixwwwwww]

ok i replace it with the correct one

[Walter Roberson]

This code does not change the structure, just finds the equivalent strings.

[5mid]

Yes true, but with that I've done what I want.

Answer 2

Assuming ISO-8859-1 rather than full Unicode:

This code is untested.

function new_structure = remove_accents_from_struct(old_structure)

    % Note: this code is only designed for size(structure) = 1 x 1
    % and does not descend recursively into substructures.

    old_fields = fieldnames(old_structure);
    new_fields = cellfun( @remove_accents_from_string, old_fields, 'Uniform', 0);

    if isequal(old_fields, new_fields)     %optimization when there are no accents
      new_structure = old_structure;
      return
    end

    num_fields = length(old_fields);

    % create empty structure populated with the translated field names but not their contents

    new_structure = cell2struct( cell( num_fields, 1 ), new_fields );

    % now copy the field contents over

    for K = 1 : num_fields
      new_structure.(new_fields{K}) = new_structure.(old_fields{K});
    end

end

function newS = remove_accents_from_string(S)
  % table extracted from     % http://core.trac.wordpress.org/browser/tags/3.7.1/src/wp-includes/formatting.php

    accented_chars = [ ...
      char(128), char(131), char(138), char(142), char(154), ...
      char(158), char(159), char(162), char(165), char(181), ...

    unaccented_chars = 'EfSZszYcYuAAAAAACEEEEIIIINOOOOOOUUUUYaaaaaaceeeeiiiinoooooouuuuyy';

    newS = S;
    [tf, idx] = ismember(S, accented_chars);
    newS(tf) = unaccented_chars(idx);
  end

[5mid]

Wow to much complex, but should work

[Walter Roberson]

You said you could have an accent on any letter, so I could not assume that you only want to deal with grave accents on English vowels.

Most of the rest of the length is comments or efficiency.
