why 'de2bi()' & 'bi2de()' functions don't work here although they work in MATLAB online?!

whereas str2double(dec2bin(x) succeeds, I dont agree it is correct.
str2double(dec2bin(10)) -> 1010
str2double(dec2bin(10)) + 2 -> 1012 ;
this makes little sense in decimal nor in binary code.

I suggest correcting the check to y_correct ='1010'

function y = dec_bin(x)
y = str2num(dec2bin(x));
end

Why doesn't the built in function dec2bin() work here?

dec2bin returns a character vector, the answer must be an int type
