1 Mathematica Functions

This chapter describes interface functions for Mathematica ox server ox_math. These interface functions are defined in the file ‘mathematica.rr’. You need to load the file before using the interface functions. by the command load("m")$. The file ‘mathematica.rr’ is at ‘$(OpenXM_HOME)/lib/asir-contrib’.

Note: ox_reset does not work.

[258] load("mathematica.rr")$

1.1.3 mathematica.rtomstr

mathematica.rtomstr(t)

:: translate the object t into a string that can be understandable by Mathematica as far as possible.

return

String

t

Object

[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}}

Let us see one more example. The following function mathematica.inverse(M) outputs the inverse matrix of the matrix M by calling ox_math. It translates asir matrix M into a Mathematica expression by r_tostr(M) and makes Mathematica compute the inverse matrix of M by ox_execute_string.

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)
