List Functions These functions are for list data stored in list variables. See

chapter 7, Using Lists.

Loop Functions The loop functions display a result after evaluating an

expression a given number of times.

ITERATE Repeatedly (the specified dimes') evaluates an expression in

terms of variable. The value for variable is updated each time,

starting with initialvalue.

ITERATE {expression, variable, initialvalue, ^imes)

RECURSE Provides a method of defining a sequence without using the

Symbolic view of the Sequence aplet.

RECURSE {sequencename, term-n, terml, term2)

Example: RECURSE (U,u (N-1) *N, 1,2) {{ST0^}}U1 (N)

This produces the factorial

ui(1)=1

Ul(2)=2

U1(N)=U1(N-1)*N

2 Summation. Finds the sum of expression with respect to variable

from initialvalue to finalvalue.

2 (variable=initialvalue, finalvalue, expression)

Example:2(C=l, 5,C^) returns55.

Matrix These functions are for matrix data stored in matrix variables.

Functions See chapter 8, Using Matrices.
