To set up the table, create it (right click the object under
which it is to be placed and select "Add New, Table". The
table values can then be imported from a text or csv file by right
clicking on the object and selecting Load... or Paste.
The expected format is a file with n numbers on each line.
The first n-1 numbers are the keys used to lookup in the
table, and the last number is the value to return. (n
should be the same on each line.) Optionally the first line can
contain column names as text. Some limited editing is possible in
the constants window; for more flexible editing copy and paste ito
a spreadsheet or text editor.
In expressions, the table behaves as a function with the same
name as the table object, and n-1 arguments. The default
name is simply Table, so a call might look like:
and a matching data file might look like:Table(J',J")
J' J" Value
0 1 0.5
1 2 1.5
In evaluating the function a simple scan of the table is done, looking for an exact match of all n-1 arguments. If no match is found, the function returns 0. For a more complicated example see CH3simplevibBX.pgo described in The B-X Transition in CH3.
|Debug||Write the values of the input variables and the value returned on each look up in the table to the log window. Note that this can produce a lot of output.|
