28 March 2023 7:54:05.922 PM legendre_fast_rule(): FORTRAN90 version Compute a Gauss-Legendre rule for approximating Integral ( b <= x <= b ) f(x) dx of order N. The computed rule is written to 3 files: leg_oN_w.txt - the weight file leg_oN_x.txt - the abscissa file. leg_oN_r.txt - the region file. The requested order N 15 The left endpoint A is 0.00000 The right endpoint B is 2.00000 Computation required 0.760000E-04 seconds. Weight file will be "leg_o15_w.txt". Abscissa file will be "leg_o15_x.txt". Region file will be "leg_o15_r.txt". legendre_fast_rule(): Normal end of execution. 28 March 2023 7:54:05.923 PM
