Test clenshaw_curtis_rule(). clenshaw_curtis_rule(): MATLAB/Octave version 9.8.0.1380330 (R2020a) Update 2 Compute a Clenshaw Curtis rule for approximating Integral ( A <= x <= B ) 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 = 5 A = -1.000000 B = 1.000000 FILENAME = "cc_o5". Creating quadrature files. "Root" file name is "cc_o5". Weight file will be "cc_o5_w.txt". Abscissa file will be "cc_o5_x.txt". Region file will be "cc_o5_r.txt". clenshaw_curtis_rule(): Normal end of execution. clenshaw_curtis_rule_test() Normal end of execution. 07-Jan-2022 18:10:57
