On your Q&A website for instructions when using data from
an excel spreadsheet you wrote:
''First, you should save the excell file at type .txt. Then, use
the built-in function ReadList[''filename'', opts___] (ofcourse,
the directory where the file is must first be
set by using SetDirectory[c:\...]) to read in the list of data.
Then, use the built in Mathematica function Fourier[data_],
which takes lists of time-series of data assumed taken at
equal increments of time.''
I will be using data from lotus 123 so I presume the same
instructions will work for using .txt from that environment. Is
my presumption correct?
I have another question: I have two columns of 516 data points
that are presently in axis order: x,y = (energy, absorption). Can
mathematica deconvolve the single set of [x,y] data into two sets
of data [x',y'] and [x'',y''](as is often done in the FTNMR -
fourier transform nuclear magnetic resonance)? If so I would
appreciate knowing how to. I can't find instructions in our local
screen help (@LSU we
have Mathematica 3).
