sympy_matrix_tools に級数の部分展開を行うルーチンや行列の数列を扱う MatrixFunction を作った(version 0.1.0)。しかし、MatrixFunction はかなり無理な実装なのでほとんどまともに動作しないのが残念。 .

一般的な行列の関数も扱えるようになったみたいだ。素粒子屋には嬉しい　 http://t.co/ddHvoowo.

そうか、行列を行列で微分するってかなり難しいのか。SymPy はテンソルに変換してやってるけど。ベクトルどうしとか、スカラーを行列で…なら可能…。MatrixFunction の微分とかって、ArrayDerivative(Mf(x),x) のままでいいからいけるかと思ったが、ArraySubs はないしそんな簡単な話じゃないんだな。.
