CIFER®-MATLAB Interfaces: Development and ... - Cal Poly

Appendix B: Help Documentation for Command-Line Interface
Introduction:
This document details the use of the command-line functions included in the CIFER ® -MATLAB
interface developed by NASA Ames. CIFER ® is a tool, also developed by NASA Ames, for
system identification using frequency responses. This document has been written assuming the
user has background in using CIFER ® . Any questions concerning the operation of CIFER ® should
be directed to the appropriate CIFER ® user manual.
This interface is designed as a tool to allow users to run CIFER ® programs and utilities from the
command line of MATLAB. This enables easy retrieval of information in CIFER ® to the
MATLAB workspace for analysis and allows the scripting of multiple batch jobs. The command
line functions will perform all the operations and checks contained in each screen of a CIFER ®
program at one time. While this allows the user great flexibility, the linear setup of the CIFER ®
screens is bypassed. Thus new users are encouraged to verify the data entered in the command
line by running the corresponding program within CIFER ® and checking each screen.
Contained within this document are a series of short examples detailing the various features and
layout of the command-line functions. These examples are supplemented by the online help
information (accessed using the command ‘help functionname’ in MATLAB) and two extended
examples, all of which are contained in this document’s appendices.
