Detailed Description

Calculate inverse of square matrix A.

This matrix can be defined on a 3-D grid or constant. The storage convention described in eq_vars.eq_2_type is used.

In the former case the size of the matrix (last two indices) should be small, as direct inversion is performed using Cramer's rule.

In the latter case, lapack routines are used.
