# scipy.linalg.funm

`scipy.linalg.``funm`(A, func, disp=True)

  Evaluate a matrix function specified by a callable.

  Returns the value of matrix-valued function `f` at A. The function `f` is an extension of the scalar-valued function func to matrices.

  Parameters : | A : (N, N) array_like Matrix at which to evaluate the function func : callable Callable object that evaluates a scalar function f. Must be vectorized (eg. using vectorize). disp : bool, optional Print warning if error in the result is estimated large instead of returning estimated error. (Default: True)
  Returns : | funm : (N, N) ndarray Value of the matrix function specified by func evaluated at A errest : float (if disp == False) 1-norm of the estimated error, ||err||_1 / ||A||_1
