'This sheet is used to compute the matrix B from the paper Stable symmetric polynomials and the Schur-Agler class. It would help to refer to equation (3.4) from the arxiv version of that paper.'
"The matrix B has its rows and columns indexed by subsets of {0,1,2,...,d-2}. I found it convenient to represent the subsets using binary expansions. The following function just gives the number of 1's in the binary expansion of a natural number (which would correspond to the size of a subset)."
'For example, the subset {0,2,3} of {0,1,..,4} would correspond to the bitstring 01101 = 1+2^2+2^4=21, and bitsize(21) would give 3.'
3
'This next function returns the location of the 1 furthest to the right in a binary expansion. Again, 21 = 01101 and so findbit(21) should return 0. While findbit(16) should return 4 since 16=10000 in binary and 1 is in the 2^4 place.'
(0, 4)
'This next function gives the matrix B from the paper Stable symmetric polynomials and the Schur-Agler class. See equation (3.4) from the arxiv version (which may differ in older versions). The input is a vector of coefficients of a polynomial and the output is the corresponding matrix B.'
'For example if my polynomial is p(z) = 1-z=1+(-1)z+0z^2+0z^3+0z^4 which I want to view as a polynomial of degree at most 4 (the degree is important for symmetrization) I could set:'
'Then, the following command would give me an array of the matrix B, which I need to convert into a matrix'

'Unfortunately the ordering of the index set for the rows and columns differs from the paper (and this makes it difficult to see all of the symmetry. Rows and columns are indexed by subsets of {0,1,2}. The ordering is given by converting numbers into binary expansions and then viewing binary expansions as subsets. So, 0,1,2,3,4,5,6,7 have binary expansions 000, 001, 010, 011, 100, 101, 110, 111 and these correspond to the subsets {}, {0}, {1}, {0,1}, {2}, {0,2}, {1,2}, {0,1,2}. And this is how the index set for the rows and columns is ordered.'
