asinhm matrix hyperbolic inverse sine

## Syntax

    t=asinhm(x)

## Arguments

x, t

  a real or complex square matrices

## Description

`asinhm` is the matrix hyperbolic inverse sine of the matrix `x`. Uses the formula `t = logm(x+sqrtm(x*x+eye()))`. Results may be not reliable for non-symmetric matrix.

## Examples

    A=[1,2;2,3]
    sinhm(asinhm(A))
