The user specifies ORDER, A, B, and FILENAME. ORDER is the number of points. A is the left endpoint (typically 0). B is the exponential scale factor (typically 1). 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 A = 0.000000 B = 1.000000 FILENAME = "lag_o4". Creating quadrature files. "Root" file name is "lag_o4". Weight file will be "lag_o4_w.txt". Abscissa file will be "lag_o4_x.txt". Region file will be "lag_o4_r.txt". LAGUERRE_RULE: Normal end of execution. 07-Jan-2022 22:40:23 laguerre_rule_test(): Normal end of execution. 07-Jan-2022 22:40:23
