why are these values not equal?

>> xx = temp_ComplexArray_12_0 * [MMSEInterfCgema{85351:85500}];

>> zz = MMSEFactor' * [MMSEInterfCgema{85351:85500}];

>> find(MMSEFactor'~=temp_ComplexArray_12_0)

ans =

   Empty matrix: 0-by-1

>> find(vpa(MMSEFactor',10000) ~= vpa(temp_ComplexArray_12_0,10000))

ans =

   Empty matrix: 0-by-1

>> zz(1,2),xx(1,2),zz(1,2)-xx(1,2)

ans =

      2.190108828498517e-08 - 2.547437668329938e-08i

ans =

      2.190108828498517e-08 - 2.547437668329917e-08i

ans =

                          0 - 2.117582368135751e-22i

WHY zz is not equal to xx ? version ： 2012a

THANK YOU~ if you can explain it
