2014-11-13 20:22:49 +0200 | asked a question | Bizarre error I'm sorry that the function in question is rather messy, but the problem is rather specific. I'm setting a constant 'c' and evaluating the local maximum of a function like so: In this case, I get the expected output. If I set Now, if I set It's also worth noting that What could be causing this problem? Is there a workaround or a potential bug fix? |

2014-11-13 19:50:09 +0200 | commented answer | Unable to coerce to real That works in this case. I have another problem, but I think it deserves a new question, so I'll ask it there. |
2014-11-13 18:08:45 +0200 | asked a question | Unable to coerce to real I'm having trouble with the find_local_minimum and find_local_maximum functions on the absolute value of a complex function. For instance, the following code is logical and works mathematically, but not in Sage: But alas, I get the error: I've also tried adding an explicit conversion to real (desperate times): This gave the same error. How do I get around this issue? And is there the possibility that this could be resolved in the Sage codebase? It seems feasible, since the plot function works just fine with the exact same function. |
