PFC instructions

[0racle2]

Where are the PFC instructions and why is it not shown in the manual？For example, pfc.pairing(P,Q). Where is the similar function description？

[mcarrickscott]

See comments in the example programs, also read pairings.txt It should be clear that pfc.pairing(P,Q) calculates a pairing (?) Mike

Thank you for your answer. I mean, is there any detailed documentation for more related operations, such as how to obtain the horizontal coordinate of a point on an elliptic curve?

As can be seen the PFC class is lightly layered over the basic miracl functions. See pairing_3.h for example. Note that all class members (of G1, G2, GT) are public. Therefore it is perfectly possible to access lower level functionality if that is desired. For example to access the (x,y) coordinates of a point.
