Inputs

p: path to extract filename from

Outputs

filename (including suffix) without directory

function f = filename(p, backend)
if nargin < 2
  backend = 'fileparts';
end

% fileparts is 5x to 10x faster than regexp and pattern
switch backend
  case 'fileparts'

    f = stdlib.append(f, ext);
% the pattern backend is a litle slower than regexp. Commented out for < R2020b compatibility
  % case 'pattern'
  %   f = extractAfter(p, asManyOfPattern(wildcardPattern + ("/" | filesep)));
  case 'regexp'

  otherwise
