You can create custom coefficient data using third-party tools such as Microsoft Excel
or the MATLAB Array Editor. To do so, click Preview coefficients under Vertical
Coefficient Data and Horizontal Coefficient Data, copy the data from the predefined
coefficient spreadsheet, edit the data with your third-party tool, delete the Phase
column, and store the data in the Coeff columns as a .csv file. Then in the parameter
editor, select Custom from the Filter function list, click Browse, load the .csv file, and
click Preview coefficients to verify the data.

Specifies the number of integer bits for the fixed-point type used to store
the horizontal coefficients.
Specifies the number of fractional bits for the fixed point type used to
store the horizontal coefficients.
Turn on to load the coefficient data at runtime.
Turn on to map horizontal and vertical coefficients to the same
memory. When on and Load coefficient data at runtime is also
on, writes to the vertical coefficients are ignored. (The choice of
read bank remains independent for horizontal and vertical
coefficients.)
Choose the number of coefficient banks to enable double-
buffering, fast coefficient swapping or direct writes.
You can choose from 12 pre-defined Lanczos functions or use
the coefficients saved in a custom coefficients file.
When a custom function is selected, you can browse for a
comma-separated value file containing custom coefficients. Use
the Preview coefficients button to view the current coefficients
in a preview window.
Turn on to save coefficient memory by using symmetric
coefficients. When on and Load coefficient data at runtime is
also on, coefficient writes beyond phases 2 and 1 are ignored.
