plot - Tupper's self referential formulae - in MATLAB? -


i trying plot tupper's formulae in matlab. apparently seems since 'k' such large value, matlab may not accept it.

any suggestions ?

you can use symbolic toolbox compute big integers.

here code whipped plot tupper expression, inspired in part this discussion on @ metafilter:

% use symbolic toolbox represent big integer k k =  sym(['960939379918958884971672962127852754715004339660129306651505519271702802395266424689642842174350' ...

and results: resulting matlab figure

note: there's not self-referential formula; choosing differential value of k, make display other image of same size. lot more exciting if actual quine!
