### 10.2 SELFCONJUGATE Declaration

The declaration SELFCONJUGATE may be used to declare an operator to be self-conjuate in the sense that conj(f(z)) = f(conj(z)). The syntax is:

selfconjugate f1,...fn;

Such declarations are not needed for the standard elementary functions nor for the inverses atan, acot, asinh, acsch. The remaining inverse functions log, asin, acos, atanh, acosh etc. and sqrt fail to be self-conjugate on their branch cuts (which are all subsets of the real axis).
