sinhm matrix hyperbolic sine

## Syntax

    t = sinhm(x)

## Arguments

x, t

  real or complex square matrices.

## Description

`sinhm(x)` is the matrix hyperbolic sine of the matrix `x`. `t=(expm(x)-expm(-x))/2`.

## Examples

    A=[1,2;2,3]
    asinhm(sinhm(A))
    A(1,1)=%i;sinhm(A)-(expm(A)-expm(-A))/2   //Complex case
