[X,fX,eig_val,eig_vec,A,fA]=NCoptCube(f,AW) computes minimizers and the minimum of the polynomial f on an nc polydisc.

f is an NCpoly representing a polynomial.
AW: true/false whether AWbd is called.

X: from GNS - a matrix where each of its rows represents a square matrix
fX: f(X) where X is from GNS
eig_val: eigenvalues of fX
eig_vec: corresponding eigenvectors
A: from AWbd
fA: f(A) where A is from AWbd - actually on each block of A
