Given a table of the form
| a | b | c |
|[2,3] | [4,6] | formula
What is the formula for column C such that elementwise division is
performed to obtain [2,2]. I realize I've to use the (calc-map OPR)
function but I am not an expert in elisp. Thanks for reading.
Regards,
Nishan

Try
| a | b | c |
| [2,3] | [4,6] | [0.5, 0.5] |
#+TBLFM: @2$3=map(div,$1,$2)
