symmetrical character array with only letters
显示 更早的评论
Im trying to make a function that gives a logical true if the character array is symmetrical and logical false if not.
So far I have:
a = 'abba'
isItSym = isequal(a(:),flip(a(:)))
res = isItSym
But for anything that is not A-Z or a-z it needs to come back as logical false and it does not (ex: 'p##p').
Im thinking some sort of if function with an sprintf to split the array up and then find any false values with char(0:64) and so on. Im a little new with matlab tho so im having trouble goin about this. Thanks!

Use isstrprop():
a = 'abba';
isItSym = isequal(a(:),flip(a(:))) && all(isstrprop(a(:),'alpha'))
a = 'p##p';
isItSym = isequal(a(:),flip(a(:))) && all(isstrprop(a(:),'alpha'))

a = 'abba';
isItSym = ~isempty(a) && isequal(a(:),flip(a(:))) && all(isstrprop(a(:),'alpha'))
a = 'abbc';
isItSym = ~isempty(a) && isequal(a(:),flip(a(:))) && all(isstrprop(a(:),'alpha'))
a = 'a##a';
isItSym = ~isempty(a) && isequal(a(:),flip(a(:))) && all(isstrprop(a(:),'alpha'))
a = '';
isItSym = ~isempty(a) && isequal(a(:),flip(a(:))) && all(isstrprop(a(:),'alpha'))
