I have looked for an answer but was unable to find one anywhere so I'm asking it here.
I am making a very simple iterative algorithm for which the input as well as the output at the end of every iteration is a vector (or matrix for that matter). What I want to do is use these elements as arguments for several functions during each of the iteration. So for example
x=var('x')
y=var('y')
z=matrix(2,1,[ [1],[1] ]
f=x^2+y^3
H=f.hessian()
Then what I would like to do is say
H(z[0],z[1])
or
H(z)
But no matter what I try I can't seem to get it to work. Ideas?DisneySageFri, 26 Nov 2010 10:44:53 +0100https://ask.sagemath.org/question/7774/
