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]]] [261] |
