Of course, this only works if the types of the elemental function and the
function itself match.

Note that matmul does not seem inlined for the test in comment 0: I see
call __gfortran_matmul_c4
in the assembly.

For large matrices it would be even better to do
c(i,j) = conjg(c(i,j))
after c(i,j) has been computed.
