Loop functions

ITERATE

RECURSE

The loop functions display a result after evaluating an

expression a given number of times.

Repeatedly for Mines evaluates an expression in terms of

variable. The value for variable is updated each time, starting

with initialvalue.

ITERATE {expression, variable, initialvalue,

#times)

Example

ITERATE (X^,X, 2,3) returns 2 56

Provides a method of defining a sequence without using the

Symbolic view of the Sequence aplet. If used with I (“where”),

RECURSE will step through the evaluation.

RECURSE (sequencename, term-n, term! , term2)

Example

RECURSE(U,U(N-1)*N,1,2)Hffl3ul(N)

Stores a factorial-calculating function named UI.

When you enter Ul ( 5), for example, the function

calculates 5 ! (12 0).

Summation. Finds the sum of expression with respect to

variable from initialvalue to finalvalue.

5) {variable=imtialvalue, finalvalue, expression)

Example

S(C=1,5,c2) returns 55.

Matrix functions

These functions are for matrix data stored in matrix variables.

See “Matrix functions and commands” on page 12-9.
