NAME

       tabfunc - convert table to functions for rcalc, etc.

SYNOPSIS

       tabfunc [ -i ] func1 [func2 ..]

DESCRIPTION

       Tabfunc  reads  a  table of numbers from the standard input and converts it to an expression suitable for
       icalc(1), rcalc(1) and their cousins.  The input must consist of a M x N matrix  of  real  numbers,  with
       exactly  one  row  per  line.   The  number of columns must always be the same in each line, separated by
       whitespace and/or commas, with no missing values.  The first column is always the  independent  variable,
       whose value indexes all of the other elements.  This value does not need to be evenly spaced, but it must
       be either monotonically increasing or monotonically decreasing.  (I.e. it cannot go up and then down,  or
       down  and  then  up.)  Maximum input line width is 4096 characters and the maximum number of data rows is
       1024.  Input lines not beginning with a numerical value will be silently ignored.

       The command-line arguments given to tabfunc are the names to be assigned to each  column.   Tabfunc  then
       produces a single function for each column given.  If there are some columns which should be skipped, the
       dummy name "0" may be given instead of a valid identifier.  (It is not necessary to specify a dummy  name
       for extra columns at the end of the matrix.)

       The -i option causes tabfunc to produce a description that will interpolate values in between those given
       for the independent variable on the input.

EXAMPLE

       To convert a small data table and feed it to rcalc for some calculation:

         rcalc -e `tabfunc f1 f2 < table.dat` -f com.cal
