of scientific and technical data. DADiSP is designed to handle all of the phases
associated with the acquisition and display of data, from initial collection to
final analysis.
DADiSP can be used to analyse and display up to 100 windows from the
same (or different) data files. The package offers a powerful graphing capabil-
ity and contains a variety of standard and advanced mathematical and statistical
functions ranging from standard arithmetic (addition, subtraction, multipli-
cation, and division) to hyperbolic functions, mean and standard deviations,
integration, and differentiation.
DADiSP uses Worksheets to display, manipulate, and analyse data in an
integrated graphic environment (Figure 10.16). Each Worksheet can display
and process information in an unlimited number of formats. In addition, each
Worksheet can be modified, rearranged, and stored as a template for future use
with other data.
Commonly used functions are grouped together and made available through
pull-down menus. However, display and data manipulation functions can also
be entered as text at the command line. DADiSP maintains a full history of
commands and lists of commands can be copied and pasted into the command
line. Using this technique it is possible to easily produce simple, yet powerful,
programs. In fact, DADiSP Worksheets behave as executable programs but
eliminate the need for traditional programming. Furthermore, Worksheets will,
updated automatically when one or more data items or Window formulae alters
so there is no need to re-run an analysis when the data changes.
DADiSP is ideally suited to any application in which captured data is to be
analysed and displayed in a graphical format. Typical examples might be X-, Y-,
and Z-axis strain developed in a structural member when subjected to repeated
cycles of stress or variation in oscillator frequency, amplitude, and noise when
