SYMPTOMS
In Microsoft Excel, when you use the Fourier Analysis tool, provided
in the Analysis ToolPak add-in, to transform data in a worksheet, and
you then use the Fourier Analysis tool again and you use values previously
returned by this function as the new input range values, you receive
the following error message:
Fourier Analysis - All complex numbers must have the same suffix, either
"i" or "j".
This behavior does not occur in Microsoft Excel version 4.0.
CAUSE
This behavior occurs because any non-imaginary number that is
returned by the Fourier Analysis tool is formatted as a text value
instead of number value. Because the Input Range value used in the
Fourier Analysis tool must be formatted as a number, the error
message appears when you use this returned value as an input value in
the Fourier Analysis tool.
WORKAROUNDS
To avoid receiving this error message, do either of the following before
using the Fourier Analysis tool using an input data range that has been
returned by the Fourier Analysis tool:
- Use the Paste Special dialog box to convert the values to numbers
instead of text by doing the following:
1. In a blank cell, type "1" (without the quotation marks).
2. Select the cell containing the 1, and choose Copy from the Edit
menu.
3. Select the range that contains the values that have been returned
by the Fourier Analysis tool.
4. From the Edit menu, choose Paste Special.
5. In the Paste Special dialog box, under Paste, select Values, and
under Operation, choose Multiply. Choose OK.
-or-
- Use the following macro to enter each of the numbers in the selection
as a number value instead of a text value:
Sub Enter_Value()
Dim xCell As Object
For Each xCell In Selection
xCell.Value = xCell.Value
Next xCell
End Sub
