asinm matrix wise sine inverse

## Syntax

    t = asinm(x)

## Arguments

x

  a real or complex square matrix.

t

  a real or complex square matrix.

## Description

`t` are sine inverse of the `x` matrix. Diagonalization method is used. For non symmetric matrices result may be inaccurate.

## Examples

    A=[1,2;3,4]
    sinm(asinm(A))
    asinm(A)+%i*logm(%i*A+sqrtm(eye()-A*A))
