Editor. For a list variable, the definitions are not saved (only their resulting cell values).
You can use an expression that: For example:
Generates a series of numbers. c1=seq(x^2,x,1,5)
c1={1,2,3,4,5}
Refers to another column.
c2=2
ùc1
c4=c1
ùc2–sin(c3)
3. Press ¸, D, or C to save the
definition and update the columns.
