Constructor & Destructor Documentation

subroutine psym2::expsym2d_t::expsym2d_t	(	real(dp), dimension(2,2), intent(in)	x,
		real(dp), dimension(2,2), intent(out)	z,
		real(dp), dimension(2,2,2,2), intent(out)	zd
	)

private

Use the Taylor-series method (eigenvalues both fairly close to zero).

For a 2*2 symmetric matrix x, try to get both the z=exp(x) and dz/dx using the Taylor series expansion method.

Parameters

[in]	x	symmetric 2*2 positive-definite matrix
[out]	z	Taylor series expansion method exp(x)
[out]	zd	symmetric derivative
