#include <misc.h>
tot
numbers from -1 to 1, making sure to include -1, 1, 0, and numbers near -1, 0 and 1 (so long as tot
is sufficiently large). If gen() is called more than tot
times, it just recycles through the list again.This class is used to generate combinations of coefficients for testing the polynomial solvers.
For example, the first 15 numbers generated by an object of type gen_test_number<10> are:
0 -1.000000e+00 1 -9.975274e-01 2 -8.807971e-01 3 -1.192029e-01 4 -2.472623e-03 5 +0.000000e+00 6 +2.472623e-03 7 +1.192029e-01 8 +8.807971e-01 9 +1.000000e+00 10 -1.000000e+00 11 -9.975274e-01 12 -8.807971e-01 13 -1.192029e-01 14 -2.472623e-03
