Hello everybody, I have this code and I would like that in the cases of the switch identify if the character of a given sentence is a lowercase letter, an uppercase or an space. Thank you very much!
sentence='Hello 22';
for ch=1:length(sentence)
switch sentence(ch)
case %if it is a lowercase letter
%blahblah
case %if it is an uppercase letter
%blahblah
case %if it is an space
%blahblah
end
end

https://www.mathworks.com/help/matlab/ref/isstrprop.html is the only practical routine to use for this purpose. If you do not use it then chances become very high that your code will produce the wrong results for characters such as δ and ή and ř
