2014-11-22 11:24:55 -0500 | asked a question | Define vector valued function of a vector of symbolic variables? I have a gradient where each component may have a different number of symbolic arguments and get the following error when I run: gradL (gradL[2])(*s) (lam0 I need to be able to to be able to define this as a vector valued function of a vector so that I can evaluate it using the entire argument set (lam0, x0, x1) where the missing arguments are ignored for the corresponding component. This is so I can def a function for scipy.optimize like: def F(s): I can't figure out how to accomplish this. Thanks for any help in advance. -Steve |

2013-04-06 05:57:22 -0500 | asked a question | field extensions in python You can define a field extenion at the sage prompt with however this same line in a python script yields a syntax error Note:syntax error point to < character eval also fails I also have similar problems with defining Quaternion Algebras in python so why does QC.<j> = QQ.extension(x^2+1) work at the sage prompt and not in python or with eval(string) Thanks, Steve |
