T_FFELT to T_VEC


Hello, all!
 
I have a problem:
1. I have an GF(2^r) element A, where GF(2^r) is extended finite field.
2. I want to get the coefficients of A when it is decomposing over GF(2^r) standard basis.
For example, for element a^5, where a is a primitive element of GF(4) ~ GF(2)[x]/<x^2 + x + 1>
I want to get a vector of coefficients: {1, 1}.
3. How can I do this? Problem is that A is a scalar
 
Thank you!
 
With best regards,
