我根据“Physics[Commutator]”的 maple 17 帮助中的第一个示例尝试了以下操作。有人知道怎么了?
with(Physics);
Setup(mathematicalnotation = true);
e1:=[Z[1],Z[2]][-];
Error, invalid subscript
Typesetting:-mambiguous(e1Assign(Z[1]commaZ[2])[
Typesetting:-mambiguous(Typesetting:-mstyle( - ,
executable = "false", mathcolor = "#909090",
mathvariant = "normal"),
Typesetting:-merror("invalid subscript"))])
