Iteration

How can I build up multiple arrays whose i'th elements depend on the i-1 'th element of the other arrays. MathCAD wants only to define the whole array at once - this is not what I want. I want to define the i'th element of all arrays at once then the i+1 'th and then the i+2 'th and so on.



Can anyone out there help? I am sure there must be an easy way of doing this - but I can't see it



Regards,
