sub - subtract a constant value from a table associated with a table-handle or do a point-by-point subtraction from another table-handle table.
sub operates on each element of the function table referred to by table_handle1 by either subtracting the value constant from each one or by subtracting the corresponding element of the table associated with table_handle2 from each one. If the two tables are of different sizes, the values will be interpolated relative to the length of each table prior to the subtraction. The interpolation scheme used depends upon the original setting of the optional specifier for interpolation used in the original maketable scorefile command that was used to create the table.
Returns a table-handle referring to the modified table
table1 = maketable("literal", "nonorm", 5, 1.0, 2.0, 3.0, 4.0, 5.0) table2 = maketable("literal", "nonorm", 5, 2.0, 4.0, 5.0, 8.0, 10.0) newtable1 = sub(table1, 2.0) newtable2 = sub(table1, table2)
The table-handle newtable1 will be associated with a new table that will contain the following sequence of elements:
-1.0, 0.0, 1.0, 2.0, 3.0and the elements of newtable2 will be:
-1.0, -2.0, -2.0, -4.0, -5.0
