在使用scipy.linalg.sqrtm的正半定矩阵的平方根的计算中，如何抑制复数

如何解决在使用scipy.linalg.sqrtm的正半定矩阵的平方根的计算中，如何抑制复数

假设我有一个矩阵A（这个矩阵很大，所以我在这里没有指定），然后应用scipy.linalg.sqrtm(A)，我得到以下包含复数的输出矩阵：

如何在scipy.linalg.sqrtm()的计算中抑制复数，以使输出矩阵不包含任何复数？

我进行了一次谷歌搜索，发现了6年前的以下Github PR，它建议包含funm_psd和structure="psd"之类的函数特征来评估正半定矩阵的一般矩阵函数，但是我可以似乎现在在任何地方都找不到这些功能。

任何帮助将不胜感激！

编辑： 我知道我可以在输出矩阵上使用np.real()来获取真实部分。我关心的是在期间中包括复数，平方根的计算可能会影响输出矩阵中的值，而不是仅仅除去输出矩阵中的复数。当然，除非在期间中包括或排除复数，否则平方根的计算不会对输出矩阵的值产生太大影响。有人知道是这样吗？
