| The loop functions display a result after evaluating an |
| expression a given number of times. |
ITERATE | Repeatedly for #times 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(X2,X,2,3) returns 256 |
RECURSE | Provides a method of defining a sequence without using the |
| Symbolic view of the Sequence aplet. If used with (“where”), |
| RECURSE will step through the evaluation. |
| |
| Example |
| |
| Stores a |
| When you enter U1(5), for example, the function |
| calculates 5! (120). |
Σ | Summation. Finds the sum of expression with respect to |
| variable from initialvalue to finalvalue. |
| Σ(variable=initialvalue,finalvalue,expression) |
| Example |
| Σ(C=1,5,C2) returns 55. |
These functions are for matrix data stored in matrix variables.
