Add a constant value to a table associated with a table-handle, or do a point-by-point addition with another table-handle table.


add(table_handle1, table_handle2/constant)


add operates on each element of the function table referred to by table_handle1 by either adding the value constant to each one or by summing each one with the corresponding element of the table associated with table_handle2. If the two tables are of different sizes, the values will be interpolated relative to the length of each table prior to the addition. 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.

NOTE: The functionality of add has largely been duplicated by the pfield-enabled capabilities of RTcmix instruments. However, the add function is still useful for Perl and shell-script front-ends to RTcmix.



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 = add(table1, 2.0)
   newtable2 = add(table1, table2)

The table-handle newtable1 will be associated with a new table that will contain the following sequence of elements: 3.0, 4.0, 5.0, 6.0, 7.0. The elements of newtable2 will be: 3.0, 6.0, 8.0, 12.0, 15.0.
