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
