Synopsis
#include <flint/fmpz_mpoly_factor.h>void fmpz_mpoly_to_mpolyl_perm_deflate(fmpz_mpoly_t A, const fmpz_mpoly_ctx_t lctx, const fmpz_mpoly_t B, const fmpz_mpoly_ctx_t ctx, const slong * perm, const ulong * shift, const ulong * stride)sourcevoid fmpz_mpoly_from_mpolyl_perm_inflate(fmpz_mpoly_t A, flint_bitcnt_t Abits, const fmpz_mpoly_ctx_t ctx, const fmpz_mpoly_t B, const fmpz_mpoly_ctx_t lctx, const slong * perm, const ulong * shift, const ulong * stride)sourceConvert from ctx to the context lctx, whose variable k is variable perm[k] of ctx with exponents mapped by e \mapsto (e - s)/t for the shift s and stride t of that variable, and back, packing the result into Abits bits. The results are sorted. See mpoly_to_mpolyl_perm_deflate.
