It looks like it goes in this order:
input_Range,output_range,inverse,labels_in_first_r ow

When I recorded a macro and selected a couple of ranges, I got:

Application.Run "ATPVBAEN.XLA!Fourier", ActiveSheet.Range("$A$1:$A$8"), _
ActiveSheet.Range("$B$1:$F$7"), False, False

entered an input range, so I examined the macro code. I didn't see my input
range in the code, but I realised I didn't know how the Fourier Analysis
application had to be called from Visual Basic anyway.

The macro recorder had inserted the line:
Application.Run "ATPVBAEN.XLA!Fourier", , , False, False
for forward Fourier transformation, and
Application.Run "ATPVBAEN.XLA!Fourier", , , True, False
for inverse Fourier transformaiton.

Can anyone who has used the Fourier Analysis tool from Visual Basic help me
by describing the syntax for calling Fourier Analysis (ATPVBAEN.XLA!Fourier)?

Many thanks.
