对方程和子方程的一个引用

Question

在我的文档中，我需要引用两个方程式和子方程式的总体标签。我在文档结构中包含了 hyperref 和 cleverref 包。但是 latex 给出了错误。

References `eq:MSE2' and `eq:abc' in reference range on page 3 have different types `equation' and `subequation'

因此，不可能有对方程及其子方程的总体标签的引用。

有人知道如何用一个命令解决这个引用吗？

提前致谢。

Answer 1

您需要这样做\label[equation]{eq:abc}，因为当前计数器是subequation。
