11 May 2025 07:45:21 PM CCN_RULE C++ version Compiled on May 11 2025 at 19:45:20. Compute one of a family of nested Clenshaw Curtis rules for approximating Integral ( -1 <= x <= +1 ) f(x) dx of order N. The user specifies N, A, B and FILENAME. N is the number of points. A is the left endpoint. B is the right endpoint. FILENAME is used to generate 3 files: filename_w.txt - the weight file filename_x.txt - the abscissa file. filename_r.txt - the region file. N = 9 A = -1 B = 1 FILENAME = "ccn_o9". Creating quadrature files. Root file name is "ccn_o9". Weight file will be "ccn_o9_w.txt". Abscissa file will be "ccn_o9_x.txt". Region file will be "ccn_o9_r.txt". CCN_RULE: Normal end of execution. 11 May 2025 07:45:21 PM
