# scipy.linalg.sqrtm

`scipy.linalg.``sqrtm`(A, disp=True)

  Matrix square root.

  Parameters : | A : array, shape(M,M) Matrix whose square root to evaluate disp : boolean Print warning if error in the result is estimated large instead of returning estimated error. (Default: True)
  Returns : | sgnA : array, shape(M,M) Value of the sign function at A (if disp == False) : errest : float Frobenius norm of the estimated error, ||err||_F / ||A||_F

  Notes

  Uses algorithm by Nicholas J. Higham
