2020-01-15 10:59:29 +0200 | asked a question | matrix base ring changes by a complex multiplication The complex multiplication of matrix changes the base ring. The result is So the multiplication by an imaginary number breaks the CDF property. This is very inconvenient for numerical calculations, because the symbolic computation is very slow. |

2016-02-13 09:01:57 +0200 | commented question | numerical value of hypergeometric function The special value of the hypergeometric 2F1 can be found in http://mathworld.wolfram.com/HypergeometricFunction.html (this page) or maybe its reference. By the way, 8/6 in my posting is typo.ã€€Correctly, this is 8/5. |

2016-01-31 21:07:42 +0200 | asked a question | numerical values of hypergeometric function fails? I want to compute the value of hypergeometric 2F1 like this. Sage math answered 16.9608452387059. But this should be 8.0/5=1.6000000. |

2016-01-31 21:07:41 +0200 | asked a question | numerical value of hypergeometric function I want to compute the value of hypergeometric 2F1 like this Sagemath answered 16.9608452387059. But this should be 8/5=1.60000000. All the other numerical values are also unreliable. I hope this will be fixed in the next version. |
