## pow2orthmatrix

Power to orthogonal matrix.

Power to orthogonal matrix.

W = pow2orthmatrix(M)

W = pow2orthmatrix(M) returns the inverse of V matrix, where V is such that XV = P, X = [x^0, x^1, ...] is the power series and P = [P_1, P_2, ...] is the orthogonal basis. This is a more stable way to compute better than V^-1, inv(V) or I\V.

M = matrix suth that PMa = xP (double matrix), or M = itau object.

W = inverse of V (double matrix).
