# scipy.linalg.sinhm

scipy.linalg.sinhm(A)

  Compute the hyperbolic matrix sine.

  This routine uses expm to compute the matrix exponentials.

  Parameters:
    A(N, N) array_like

      Input array.

  Returns:
    sinhm(N, N) ndarray

      Hyperbolic matrix sine of A

  Examples

      >>> import numpy as np
      >>> from scipy.linalg import tanhm, sinhm, coshm
      >>> a = np.array([[1.0, 3.0], [1.0, 4.0]])
      >>> s = sinhm(a)
      >>> s
      array([[ 10.57300653,  39.28826594],
             [ 13.09608865,  49.86127247]])

  Verify tanhm(a) = sinhm(a).dot(inv(coshm(a)))

      >>> t = tanhm(a)
      >>> c = coshm(a)
      >>> t - s.dot(np.linalg.inv(c))
      array([[  2.72004641e-15,   4.55191440e-15],
             [  0.00000000e+00,  -5.55111512e-16]])
