Extracting columns from a matrix and storing each column in a separate file
Hi All,
I have a huge matrix file consisting some some millions rows and 6000 columns. The contents are just floating point numbers in the matrix. I want to extract each column (i.e. 6000 of them) and store each column in a separate file.
For example, 1.dat will consist of elements from column 1. 2.dat will have the numbers from the 2nd column and so on. I have tried this but it does not work:

tabfunc
TABFUNC(1) General Commands Manual TABFUNC(1)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 increas-
ing 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
