MATLAB: Is there an inverse of the Galois field gf function

Question

If I have an array A that is converted to a GF(2) using gf(A) to give A_g, and I then do operations on A_g such as encoding and reshaping to produce B_g, how can I convert B_g to a normal array like A to produce B. In essence I'm asking what is the inverse of function gf

Answer 1

A_g.x

This might be undocumented. The property name is not obvious... but it works.
