Save FFT File

This option provides the facility to save FFT data into a file. This data may subsequently be reloaded by [L Load FFT file].

Save data to what file (.FFT default extension) ?

This entry specifies the name of the file to which the data will be saved. The data will be that currently in the internal memory array.

Title for file ?

The data may be given an optional title string which is specified by this entry. This title will be written to the file.

Horizontal cut-off wave number (0 for all) ?

This entry allows a subrange of the wave numbers to be saved. If a positive value is specified, then only the Fourier components with horizontal wave numbers less than or equal to the specified value will be saved. Specifying -1 will allow all horizontal wave number components to be saved.

Vertical cut-off wave number (0 for all) ?

This entry allows a subrange of the wave numbers to be saved. If a positive value is specified, then only the Fourier components with vertical wave numbers less than or equal to the specified value will be saved. Specifying -1 will allow all vertical wave number components to be saved.
