Fortran Data Types Accessing complex components
Example
The complex entity
complex, parameter :: x = (1., 4.)
has real part 1. and complex part 4.. We can access these individual components as
real(x) ! The real component
aimag(x) ! The complex component
x%re ! The real component
y%im ! The complex component
The x%.. form is new to Fortran 2008 and not widely supported in compilers. This form, however, may be used to directly set the individual components of a complex variable
complex y
y%re = 0.
y%im = 1.
