6.3.1 Using Intersci

In the following, we will only consider Fortran subroutine interfacing. The process is nearly the same for C functions (see 6.3.1).

To use Intersci execute the command:
intersci <interface name>
where <interface name>.desc is the file describing the interface.

The intersci script file is located in the directory SCIDIR/bin.

Then the interface file <interface name>.f is created. A Scilab script file .sce is also created. This file, with appropriate changes, can be used to link the interface with Scilab.

The file <interface name>.desc is a sequence of descriptions of pairs formed by the Scilab function and the corresponding Fortran subroutine (see table 6.1).

 

Table 6.1: Description of a pair of Scilab function and Fortran subroutine

< Scilab function name> < function arguments>

< Scilab variable> < Scilab type> < possible arguments>

    $\vdots$                $\vdots$                $\vdots$                $\vdots$                 $\vdots$

< Fortran subroutine name> < subroutine arguments>

< Fortran argument> < Fortran type>

    $\vdots$                $\vdots$                $\vdots$                $\vdots$

out < type> < formal output names>

< formal output name> < variable>

    $\vdots$                $\vdots$                $\vdots$                $\vdots$

*******************************

 

Each description is made of three parts:

• description of Scilab function and its arguments
• description of Fortran subroutine and its arguments
• description of the output of Scilab function.
