user - interfacing a Fortran or C routine
With this command it is possible to use an external program as a Scilab command where (s_1,s_2,...,s_lhs) are the output variables and (e_1,e_2,...,e_rhs) are the input variables. To insert this command in Scilab one has to write a few lines in the user fortran subroutine of Scilab. See intersci or the Scilab documentation for more information.
