Added data for H^10_1(1,y) without gauge transformation to avoid an error of linear interpolation of , e.g., tk_ode_assert.get_linear_linear_interpolation_value("h",3.97)*exp(3.97)*3.97^10. Use tk_ode_assert.get_linear_interpolation_value("hn",3.97) instead.

tk_ode_assert.hkn2() ... follow the instruction displayed ... tk_ode_assert.output_relative_error("h2","t.txt" | zoom=10^4301) generates tmp-rerror.txt of the relative error of H^k_n. See tk_ode_assert.usage_assert() for details.

A C program generator for a numerical solver of ODE with some heuristics to avoid instability. Example: Solving the Airy differential equation: --> load("tk_ode_by_mpfr.rr"); --> Code=tk_ode_by_mpfr.code_solve_ode_by_rk4_with_defuse([[0,1],[t,0]], 0,[0.355028053887817,-0.258819403792807],10.1 | h=0.001)$ --> util_write_string_to_a_file("tmp-test.c",Code)$ On the unix shell ln -s ${OpenXM_HOME}/lib/asir-contrib/tk_ode_by_mpfr/proj.c tmp-proj.c cc -I${OpenXM_HOME}/lib/asir-contrib/tk_ode_by_mpfr -DNN=2 -c tmp-proj.c cc -o tmp-test tmp-test.c tmp-proj.o -lmpfr -lgmp -lgsl -lgslcblas -lm ./tmp-test --verbose --t_noproj 8.1 --n_defuse 2000 --n_prune 1
