Constructor & Destructor Documentation

subroutine psym2::invsym2::invsym2	(	real(dp), dimension(2,2), intent(in)	em,
		real(dp), dimension(2,2), intent(out)	z
	)

private

		real(dp), dimension(2,2,2,2), intent(out)	zd
	)

private

Get the inverse, z,of a 2*2 symmetric matrix, em, and its derivative, zd, with respect to symmetric variations of its components.

I.e., for a symmetric infinitesimal change, delta_em, in em, the resulting infinitesimal change in z would be:

delta_z(i,j) = matmul(zd(i,j,:,:),delta_em)

Parameters

[in]	em	2*2 symmetric matrix
[out]	z	inverse of a 2*2 symmetric matrix
[out]	zd	derivative of the 2*2 symmetric matrix
