gen_test_number
¶ Generate number sequence for testing.
A class which generates
tot
numbers from -1 to 1, making sure to include -1, 1, 0, and numbers near -1, 0 and 1 (so long astot
is sufficiently large). If gen() is called more thantot
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
This function is used in
src/other/poly_ts.cpp
which tests the polynomial solvers.- Idea for Future:
Document what happens if
tot
is pathologically small.
