[sage-devel] Re: Request for matrix() to try _matrix_(), similar to vector()

Ack, I'm an idiot. The functionality is there in matrix(), I just need to add _matrix_ to the vector classes. Will do that instead :) BTW, the matrix() documentation is not right -- it doesn't say this. Nick On Dec 17, 8:30 pm, Nick Alexander <[EMAIL PROTECTED]> wrote: > Hi everyone, > > I fre

[sage-devel] Request for matrix() to try _matrix_(), similar to vector()

Hi everyone, I frequently want to get column vectors, and vector([2, 3]).transpose () is not implemented. One then thinks of matrix(vector([2, 3])).transpose(), but matrix() is a little rigid. Looking at vector, there is a protocol that calls _vector_() if possible; I would like that to

I seem to remember that Maple has a function "unapply" which when applied to a symbolic expression with one variable, returns a callable function, e.g. unapply(t*cos(0)) would return a callable function t -> t*cos(0). I cannot remember if it could handle symbolic expressions with more than one va
