conj, conjf, conjl - calculate the complex conjugate
#include <complex.h> double complex conj(double complex z); float complex conjf(float complex z); long double complex conjl(long double complex z); Link with -lm.
These functions return the complex conjugate value of z. That is the value obtained by changing the sign of the imaginary part. One has: cabs(z) = csqrt(z * conj(z))
These functions first appeared in glibc in version 2.1.
For an explanation of the terms used in this section, see attributes(7). ┌──────────────────────────────────────┬───────────────┬─────────┐ │Interface │ Attribute │ Value │ ├──────────────────────────────────────┼───────────────┼─────────┤ │conj(), conjf(), conjl() │ Thread safety │ MT-Safe │ └──────────────────────────────────────┴───────────────┴─────────┘
