  By using the RT formula and the subregion CV conjecture respectively, we
numerically investigate the holographic entanglement entropy (HEE) and
holographic subregion complexity (HSC) for two holographic d-wave
superconducting models with backreactions. We find that both the HEE and HSC
can be used as good probes to these two d-wave superconducting phase
transitions. The HEE of superconducting phase is always lower than that of the
normal phase due to the condensation of degrees of freedom below the critical
temperature Tc. However, for the HSC, it behaves differently and interestingly,
which depends on both the strip-width Lx and backreaction \k{appa}.
