Bill,
That's because 0.1j appears before 0.5 in the single vector list of
complex numbers Gamma1. For the unique list of pairs, the pair (0.5
0.1j) actually appears in the list as (0.1j 0.5), because of the order
of the individual numbers in the list Gamma1. If you are searching for
that pair, you will only find it if you search for 0.1j using vlookup.
If you have a set of unique pairs, you will never find all occurrences
of a particular complex number by only searching in one column! If you
count the occurrences in both columns, you will see that 0.5 and 0.1j
appear an equal number of times.
Regards,
Jonathon

Jonathon,
Thanks for the help. There appears to be a bug in the modified program
though.
If I use vlookup(0.5,Pairs(Gamma1),1) I get a certain number of rows.
If I use vlookup(0.1*j,Pairs(Gamma1),1) I get a different number of
rows.
Same results in both Mathcad Versions 11 and 13.
Bill
