acoshm(1)                      Scilab Function                      acoshm(1)
NAME
  acoshm - matrix hyperbolic inverse cosine

CALLING SEQUENCE
  t=acoshm(x)

PARAMETERS

  x,t       : real or complex square matrix

DESCRIPTION
  acoshm is the matrix hyperbolic  inverse cosine  of the matrix x.  Uses the
  formula t=logm(x+(x+eye)*sqrtm((x-eye)/(x+eye))) For non symmetric matrices
  result may be inaccurate.

EXAMPLE
  A=[1,2;3,4];
  coshm(acoshm(A))
  A(1,1)=A(1,1)+%i;
  coshm(acoshm(A))

SEE ALSO
  acosh, logm, sqrtm
