この節では Mathematica の ox サーバ ox_math
とのインタフェース関数を解説する.
これらの関数はファイル ‘mathematica.rr’
で定義されているのでこのファイルを
load("mathematica.rr")$
でロードしてから使用しないといけない.
‘mathematica.rr’ は ‘$(OpenXM_HOME)/lib/asir-contrib’ にある.
注意: ox_reset
は動かない.
[258] load("mathematica.rr")$ m Version 19991113. mathematica.start, mathematica.tree_to_string, mathematica.n_Eigenvalues [259] mathematica.start(); ox_math has started. ox_math: Portions copyright 2000 Wolfram Research, Inc.

Mathematica
is the trade mark of Wolfram Research Inc.
This package requires Mathmatica Version 3.0, so you need
Mathematica to make this package work.

mathematica.start
:: Localhost で ox_math
を起動する.
整数
ox_math
を起動する.
起動された ox_math
の識別番号を戻す.
Xm_noX =1
としておくと, ox_math
用の debug window が開かない.
M_proc
に格納される.
P = mathematica.start()

mathematica.tree_to_string
:: ox_math の戻す Mathematica の木構造データ t を asir
形式に
なおす.
文字列
リスト
ox_math
の戻す Mathematica の木構造データ.
asir
形式に
なおす.
m_
をキーワードの先頭につけて, 関数呼出形式の文字列へ
かえる.

mathematica.rtomstr
:: t をなるべく Mathematica の理解可能な文字列に変える.
文字列
オブジェクト
asir
ではリストを [
, ]
で囲むが,
Mathematica では {
, }
で囲む.
この関数はこの変換をおこなう.
[259] mathematica.rtomstr([1,2,3]); {1,2,3} [260] mathematica.rtomstr([[1,x,x^2],[1,y,y^2]]); {{1,x,x^2},{1,y,y^2}}
もう一つ例をあげよう.
次の関数 mathematica.inverse(M)
は ox_math
をよんで行列 M
の逆行列を計算する関数である.
mathematica.inverse(M)
は次のように r_tostr(M)
を用いて
asir の行列を Mathematica 形式に変換してから
ox_execute_string
で Mathematica に逆行列を計算
させている.
def inverse(M) { P = 0; A = mathematica.rtomstr(M); ox_execute_string(P,"Inverse["+A+"]"); B = ox_pop_cmo(B); C = mathematica.tree_to_string(B); return(eval_str(C)); } [269] M=[[1,x,x^2],[1,y,y^2],[1,z,z^2]]; [[1,x,x^2],[1,y,y^2],[1,z,z^2]] [270] A=mathematica.inverse(M)$ [271] red(A[0][0]); (z*y)/(x^2+(-y-z)*x+z*y)
