Do NOT use ismember
Those are floating point values. It would be an extremely bad idea to use ismember on floating point values, because ismember tests for equivalence of the values. Really bad idea:
Those values should be compared using a tolerance, or with ismembertol.

"ismembertol is used for high precised values"
Wrong. Here is a very simple example with just one decimal place:
>> ismember(0.1,0.3-0.2)
ans = 0
Like I wrote, you should use ismembertol.
