1 PHC 函数

この節では PHC pack の ox サーバ ox_sm1_phc とのインタフェース関数を解説する. これらの関数はファイル ‘phc.rr’ で定義されている. phc は ‘$(OpenXM_HOME)/lib/asir-contrib’ にある.

[255] phc.start();
0
[257] phc.phc([x^2+y^2-4,x*y-1]);
The detailed output is in the file tmp.output.*
The answer is in the variable Phc.
0
[260] Phc ;
[[[-0.517638,0],[-1.93185,0]],
[[1.93185,0],[0.517638,0]],
[[-1.93185,0],[-0.517638,0]],
[[0.517638,0],[1.93185,0]]]
