Hello, I am quite new to Sage and I have the following question. In my computations I have a quadratic form: xTAx=b , where the matrix A is defined already as a symmetric matrix, and x is defined as
W = itertools.product([0,1], repeat = n)
for w in W: w = vector(w)
as all combination of [0,1] repeated n times. I got a set of values for b and extracted few of them from the set. Now, I need to identify which x is corresponding to a particular value of b. Is there any command to do so? If it is possible. Thank you for help.
