Carroll,
I am not a math 'guru', but Mathematica, MathCad and MatLab can all do
what you are looking for. If you do not wish to learn a new program
and are happy with the results of Table Curve, I would suggest getting a
macro program for Windows. Most can do both keyboard as well as
mouse movement and clicks. The one I use is EZ Macros by American
Systems. They also have a program tha can so screen /window
capture, like Snag-It does, which is very popular. With EZ Macros,
you can edit the recorded session . So you could add files, delete
parts and the like. There is a trial version.

I have a program called TableCurve 2D which has numerous functions
for
analyzing numerical data. It has an elegant graphical interface for
user
interaction. My primary use of it is Fourier filtering or
smoothing. It
presents a histogram of the spectral composition of your data and allows
you
to delete any components you wish. I use it almost exclusively as
a
low-pass filter. One very important characteristic of the program
is that
for EVERY data point in the input there is a corresponding data point in
the
output - in other words, if N represents the value of X at the last
data
point in the input, the output also has a point at X=N. (I realize
that the
Y value at X=N may change as additional points are added beyond N, but I
can
live with that.)
Here's my problem: The user interface is elegant, but strictly
manual. I
need to be able to pass 40, 100, or more files through such a filter
(same
frequency cutoff for all) and it is simply too tedious and time-consuming
to
handle each one manually.
What I need is a program which has the above filtering capability but
which
either
(1) has some kind of macro capability permitting me to automate the
process
for many files (must be able to specify a list of input and output
file
names and the cutoff frequency or wavelength), or
(2) can be invoked from the command prompt with input and output file
names
and the cutoff value specified on the command line.
I've checked with SPSS, the firm that produces TableCurve, and they
can't
help me. Any suggestions where I might find such a program?
Regards,
Carroll S.
