To recall matrix of table contents

Whenever you press 

3

 (Reslt) while the recursion data menu is on the display, the

recursion formula numeric table appears on the screen in matrix format.

• This operation is available only from the RUN or PRGM Mode.

  Example

To recall the contents of the numeric table for recursion formula

a

n

 = 2

n

 + 1, while the table range is Start=1 and End=6

3

(Reslt)

w

• The table contents recalled by the above operation are stored automatically in

Matrix Answer Memory (MatAns).

• An error (Dim ERROR) occurs if you perform the above operation when there is

no function or recursion formula numeric table in memory.
