the values are less from eps

Hi

i run have a function of an parameter Z ( is a impedance real or imaginary ) part

the values of Z is in the range [Z1 Z2] .

The valuues of some quanties in the function are very small -2.66e-17 AND THE eps is 2.20e-16 this is a problem ?

thank you

No

i compare my values from an analytic epression and i find difference uin edn point

when i add in z1 a small number and in z2 substact a the same small number the resullts are the same ?

why?

If you add to A a number less than eps(A), it will result in no change,e .g.

A=175;

A==(A+eps(A)/2)

ans = logical
