Inthispaperweconsiderthequadraticmatrixequationwhich can be defined by Q(X) = AX^2 + BX + C = 0,where X is a n×n unknown real matrix; A,B and C are n×n given matrices with real elements. Newton’s method is considered to find the skew-symmetric solvent of the nonlinear matrix equations Q(X). We also show that the method converges the skew-symmetric solvent even if the Fr ́echet derivative is singular. Finally, we give some numerical examples.
