Lets say I have a table with columns: x1, x2, …, x1000.
And I’d like to create many other columns as a function of specific ones, lets say for example:
y1 = x1 + x3
y2 = x568 / x763
y120121 = x3 / (x999 - x1) - x750
The thing is I have a non-fixed number of columns to create related (each one) to specific inputs of the table.
Thanks for the help you could provide.
