Question

How do I replace the following special characters by their equivalent?

Vowels: ÁÉÍÓÚáéíóú by AEIOUaeiou respectively. And letter Ñ by N.

The expression:

str = regexprep(str,'[^a-zA-Z]','');

Will remove all characters non in alphabet, but how do I replace with something equivalent like shown above?

Thanks

You could write a series of regular expressions like:

s = regexprep(s,'(?:À|Á|Â|Ã|Ä|Å)','A')
s = regexprep(s,'(?:Ì|Í|Î|Ï)','I')

and so on for the rest of the accented characters… (for both upper/lower cases)

Warning: there are so many variations even for the small subset of Latin alphabet

A simpler example:

chars_old = 'ÁÉÍÓÚáéíóú';
chars_new = 'AEIOUaeiou';

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

The string before:

>> str
str =
Ámró

after:

>> str
str =
Amro
