Problem 823. Find similar/related functions

The help function can be useful for getting quick assistance on a particular function. For most built-in MATLAB functions, a portion of the help text lists similar or related functions ("See also ...").
Given a function name (string), return a cell array of the "See also" functions provided in the help text. If the input is not a real function or if no similar/related functions exist, return an empty cell array. The output should be all lowercase and in the order shown in the help text.
seeAlso('sum') = {'prod','cumsum','diff','accumarray','isfloat'}
seeAlso('fake') = {};
