Hi all, I have next code for checking CCZ-equivalence of two vectorial Boolean functions in magma: n:=7; GF:= FiniteField(2,n); a:=PrimitiveElement(GF);
// returns the linear Code with columns (1,x,f(x)) function CF(f) M:=Matrix( 2*n+1, 2^n, [1: x in GF] cat [Trace(a^i * x): x in GF, i in [1..n ]] cat [Trace(a^i * f(x)): x in GF, i in [1..n]]); return LinearCode( M ); end function; f:=func<x | x^3 >; g:=func<x | x^5 >; if IsIsomorphic(CF(f),CF(g)) eq false then "f and g are NOT equivalent"; else "f and g are equivalent" ; end if; I can't find analogue of IsIsomorphic in sage.It is the main problem of converting code to sage. Is sage has similar function? Or how to implement it?
