Dear All, Just in case somebody is interested, find attached a Scilab function to compute the sine integral function Si (the integral from 0 to x of the sinc function), which cannot be expressed in closed form with elementary functions. It is preliminary, it doesn't test for appropriate input argument. It works for real or complex matrices or N-D arrays. It can be easily modified to get the cosine integral function.

Great work, Federico! Just a comment: IMHO, so short functions
names should really be avoided. _______________________________________________ users mailing list [hidden email] http://lists.scilab.org/mailman/listinfo/users |

Of course, the same expint could then be used as well for
integral(dt.sh(t)/t), _______________________________________________ users mailing list [hidden email] http://lists.scilab.org/mailman/listinfo/users |
