tabfunc - convert table to functions for rcalc, etc.

**tabfunc** [ **-i** ] func1 [func2 ..]

*Tabfunc* reads a table of numbers from the standard input and
converts it to an expression suitable for *calc*(*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.

To convert a small data table and feed it to rcalc for some
calculation:
rcalc -e `tabfunc f1 f2 < table.dat` -f com.cal
