>> 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
