Can you use replace to remove all characters that aren't letters from a string?

I was wondering if I can use replace(str, ~['A':'Z' 'a':'z'], ' ') to replace all values that are not letters with an empty character. For example, if the string was 'I; love123 you-+'

I would need it to make a new string that is 'I love you'. Additionally, if this is not possible is there another way of doing this?

You can use isstrprop to create a mask for various categories of characters then use that mask to extract just all letters, or just all numbers, etc.

Try

str = 'I; love123 you-+';
str_new = regexprep(str,'[^a-zA-Z\s]','');

That worked! It will not let me accept the answer at the moment so I will keep trying. Thanks.
