Re: [sage-support] What is wrong with this SAGE function?

Thanks! Is there otherwise any standard operation in SAGE to create such vectors? If you have time can you also look into another question I had about vectors in SAGE: Given a vector $v$ and a matrix $A$ of dimension $n$, one would say that $v$ is a cyclic vector of $A$ if the following set

[sage-support] What is wrong with this SAGE function?

I am trying to define a function "elem" which will create me a list of length n which has 1 at the i^th position. def elem (i,n): A = [] for k in range [n-1]: if k != i: A.append([0]) if k == i: A.append([1]) return A elem (1,5) Why does the above not wo

I would like the sagemath syntax for the mathematica Plot[ a Sin[x] /.a -> 4, {x,-Pi,Pi} ]. It seems quite difficult to do a search that will yield an answer. Thanks to whomever. -- You received this message because you are subscribed to the Google Groups "sage-support" group. To unsubscribe fro
