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.

you can do it like this:
names = {};
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});
Good luck!

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

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

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;
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});
function newS = remove_accents_from_string(S)
% table extracted from %
accented_chars = [ ...
char(128), char(131), char(138), char(142), char(154), ...
char(158), char(159), char(162), char(165), char(181), ...

Wow to much complex, but should work

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.
