Description of the Change
Optimization of T_p in Region was performed in #17 that resulted in a 2.5x speed-up of that function. The same vecroirzation method was applied here to the reverse p_T function, but with only a 10% increase in speed.
Because of the last few PRs back to #51, which made the T_p function thread safe, the patch number is bumped here to 2.2.1.
Benefits
Very slight speed increase in saturation curve function T_p in Region 4, but now consistent with the reverse p_T function. Having bumped the patch version, this version will be bumped in the main CoolProp code.
Possible Drawbacks
None. Coded with lesson learned from #51 to make this change thread safe.
Verification Process
IAPWS-IF97 verification tables were generated using the top level IF97.cpp program. There were no regressions.
Applicable Issues
No related issues.
