20 March 2020 07:16:13 PM JACOBI_RULE C++ version Compute a Gauss-Jacobi quadrature rule for approximating Integral ( A <= x <= B ) (B-x)^alpha (x-A)^beta f(x) dx of order ORDER. The user specifies ORDER, ALPHA, BETA, A, B, and FILENAME. ORDER is the number of points. ALPHA is the exponent of ( B - x ); BETA is the exponent of ( x - A ); 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. ORDER = = 4 ALPHA = 0.5 BETA = 1.5 A = -1 B = 1 FILENAME is "jac_o4_a0.5_b1.5". Creating quadrature files. Root file name is "jac_o4_a0.5_b1.5". Weight file will be "jac_o4_a0.5_b1.5_w.txt". Abscissa file will be "jac_o4_a0.5_b1.5_x.txt". Region file will be "jac_o4_a0.5_b1.5_r.txt". JACOBI_RULE: Normal end of execution. 20 March 2020 07:16:13 PM
