description:[X,fX,eig_val,eig_vec,A,fA]=NCoptBall(f,AW) computes minimizers and the minimum of the polynomial f on an nc ball. arguments:f is an NCpoly representing a polynomial. AW: true/false whether AWbd is called. output: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 possible usage:NCoptBall(f), NCoptBall(f,AW) |
