In This Example
This example uses the demo Atmosphere model that comes with the Simulink
product. The following procedures require you to know how to write Fo rtran
code appropriate for the Simulink and xPC Target software. See “Creating
Fortran S-Functions” in the Developing S-Functions guideforthesedetails.
Before you start, create an x PC Target Simulink model for the Atmosphere
model. See “Creating an xPC Target Atmosphere Model for Fortran” o n page
13-5.
Creating an xPC Target Atmosphere Model for
Fortran
To create an xPC Target Atmosphere model for Fortran, you need to add an
xPC Target Scope block to the
sfcndemo_atmos model. Perform this procedure
if you do not already have an xPC Target Atmosphere model for Fortran.
1 From the M ATLAB window, change folder to the working folder, for
example,
xpc_fortran_test.
