How can I flip the sign of the real part but not affect the imaginary part of a complex number:
a+bi => -a + bi
Example list:
list = {{-0.282095 + 0.282095 I, -0.27254 + 0.291336 I,
-0.262018 + 0.300835 I, -0.250437 + 0.310542 I}}
expected:
{{0.282095 + 0.282095 I, 0.27254 + 0.291336 I,
0.262018 + 0.300835 I, 0.250437 + 0.310542 I}}
So it's "similar" to conjugate but works on the real not imaginary.
