Re: Complex numbers

[Renier Marchand <renierm@gmail.com>]

I have found the following way to reference my data correctly without
having to quote it or have data rewritten.

I do:

      #+tblname: my-data
      | hmin |
      |------|
      |      |
      | 0.05 |
      |  0.2 |
      |  0.2 |
      #+TBLFM: @5$1='(sbe "myfunc" (data "my-data[3:4,0]"))

This also works for complex data as you suggested.

But is there a way to refer in the formula to the current table
instead of a specific table? Because this would obviously not work for
multiple tables with the same name. (i.e. copy and paste for another
dataset)

Regards,

Renier
