The test suite is a little soft. I feel the addition of 'for i=log2(2):abs(n^2-n)', which should yield 'for log2' would stymie almost all the solutions provided.
In my opinion, the Cody problems should expand Matlab understanding not cause frustration in search of obscure functions. To this end, I think the tags should include regexp, symvar, cellfun, sprintf, exist, unique, and cell2mat. Learning the usage of these functions is one purpose of Cody.
also operands like +,-,/,*,.*,~,|,& etc. are treated by Matlab as builtin functions, so in my opinion test case 2 answer sholud be ': sqrt sum' and for test case 3 '- ones rand round'
Nice...unfortunately, it is not a general solution. For example: if 'x = ones(round(7.7)) - rand + b;', then this code will sniff y = 'b ones rand'.
you found it huh?:) no,it's not a general solution, I built it base on test suite.
