for an n-dimensional vector x, the function should return another vector 2n-dimension which each element is repeated twice.
in->[2 3 NaN 5] and out->[2 2 3 3 NaN NaN 5 5]
improve test suit
This solution only works for vectors that are already sorted from low to high :) but it passed the test suite
This works in R2012b, but not on cody
function ans = duplicate(x)
Return the largest number that is adjacent to a zero
Test for balanced parentheses
