### Calling Sequence

  `t=sinhm(x)`

### Parameters

- `x,t` : real or complex square matrix

### 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
