structure by default.)
4. At this stage, it is recommended to read the documentation in the FDC subdirectory
DOC. In particular, check README.TXT for important last-minute information
(this file also contains a copy of these installation instructions), and
COPYING.TXT and LICENSE.TXT for the terms of use. Other documentation files
are CHANGELOG.TXT, which describes the major changes in the last few FDC
versions, ROADMAP.TXT, which outlines past FDC developments and future
plans, and CONTENTS.TXT, which contains a complete list of FDC files.
5. StartMATLAB version 5.3 or later and use the command cd or chdir to go to the
FDC directory specified above (from now on denoted as ‘FDC root-directory’).
This has been illustrated in figure 7.1, where it is assumed that the FDC toolbox
has been installed into the directory K:\MYTOOLS\FDC14.
6. Type fdc at the command-line to run the FDC initialisation routine. The splash
screen from figure 7.2 will appear, to signal that the toolbox is being started;
click on the splash screen with the mouse pointer, or press any key to continue.1
After closing the splash screen, the command window will look like figure 7.3.
7. The toolbox will now be initialized by appending the FDC subdirectories to the
MATLAB-path. As shown in figure 7.3, you will be asked to verify the default
FDC search-path: Path ok? (y=yes, n=no, s=suppress this message in the future). If
you have followed the above instructions, it is normally sufficient to verify the
location of the FDC root-directory; the option to change subdirectory names is
meant to accommodate possible future additions to the toolbox.
8. If the displayed path differs from the actual location of the FDC directories,
answer the above question with n. The initialisation routine will direct you to
the menu shown in figure 7.4, from where you can change the root-directory,
change or delete the subdirectories, or add new subdirectories to the toolbox.
Select ‘ready’ to return to the directory-check window from figure 7.3.
9. If the FDC path is correct, you can leave the directory-check window by answering
the question from step 7 with y. This directory-check (and the directory
1The splash screen can be disabled for future sessions by commenting-out the line containing the
call fdc splash; in the file FDC.M, contained in the FDC root-directory.

editing features) can be suppressed for all future FDC sessions by answering
with s instead.1 If this latter option is selected, the initialisation routine will
ask for confirmation, as shown in figure 7.5.
10. Next, the welcome message from figure 7.6 will be shown to signal that the
toolbox has been initialized. The FDC directories have now been appended to
theMATLAB path, so all FDC programs and models can now be opened directly
from the command line, regardless of the current working directory. The main
FDC library can be accessed by typing fdclib, while the on-line helpfiles for
FDC 1.4 can be shown in a webbrowser or the MATLAB help browser by typing
browse fdc. In addition, the FDC directories will be appended to the bottom of
the list in the MATLAB help window, which can be opened by typing helpwin.
Double-clicking those directories will reveal a brief overview of their contents.
(The same information can be opened directly from the MATLAB command
line by typing help <dirname>, where <dirname> is the name of the FDC rootdirectory
or subdirectory.)
Notice that the FDC directories will not be appended to the MATLAB path permanently.
After closing MATLAB it will be necessary to repeat steps 5 to 10 from the
above list again: start MATLAB, change to the FDC root-directory, type fdc at the
command-line, and verify the directory structure. This last step can be skipped for
future FDC sessions by choosing the ‘suppress’ option in step 8.
Users who intend to use the FDC toolbox frequently, may find it convenient
to permanently append the FDC root-directory to the MATLAB path. This can be
achieved by manual editing of the MATLAB system files PARDEF.M or STARTUP.M,
or by means of the path browser, which can be started by typing editpath at the
command-line. See the MATLAB documentation for more information about the
MATLAB path [3].
In the remainder of this report we will assume that the toolbox has been properly initialized,
