clc; clear all ;
str = 'unbecomingly';
prefix = 'un'; % The prefix to remove
suffix = 'ly'; % The suffix to remove
%
str = strrep(str,prefix,'') ;
str = strrep(str,suffix,'') ;

For people stumbling upon this thread for an answer: This solution also removes parts in between the string if they happen to match the given prefix or suffix.
E.g.:
strrep('ABC01ABC123', 'ABC', '')
becomes
'01123'

try this:
str = 'unbecomingly';
prefix = 'un'; % The prefix to remove
suffix = 'ly'; % The suffix to remove
regex = {['^' prefix],[suffix '$']}; % the regular expressions for prefix & suffix
replacements = {'',''}; % Replacement strings
newstr = regexprep(str,regex,replacements); % The new string with suffix or prefix or both replaced by corresponding replacement string.
