Gauss–Legendre quadrature with n=10 just for fun :-)
Attention: Before executing the program load the csv files into lists (Statistics menu). All data stored in List25 and List26 will be lost. If you want to change the lists 25 and 26 to different ones (1 - 24), just open and delete corresponding number of the special characters (,) in the csv file.
3 files are ready for downloading: GAUSSQ.txt, Gauss.csv, GAUSSQ.g3m
