tablefunc is a special command that should be run from inside the spreadsheet. It returns the evaluation of an expression ex depending on a variable x for x=x0, x0+h,.... :
In the latter case, the default value for x0
is the default minimum value of x from the graphic configuration
and the default value for the step h is 0.1 times the difference
between the default maximum and minimum values of x (from the
Example: type Alt+t to open a spreadsheet if none are open. Then select a cell of the spreadsheet (for example C0) and to get the table of "sinus", input in the command line of the spreadsheet :
This will fill two columns with the numeric value of x and sin(x) :
Hence the values of sin(x) are on the same rows as the values of x. Note that the step and begin value and the expression may be easily changed by modifying the correspondent cell.
The graphic representation may be plotted with the plotfunc command (see 6.2.1).
