##### Command Categories (All commands)

Iteration( <Function>, <Start Value>, <Number of Iterations> )
Iterates the function n times (n = number of iterations) using the given start value.
Examples:
• After defining `f(x) = x^2` the command `Iteration(f, 3, 2)` gives you the result (32)2 = 81.
• Repeated addition: To obtain the repeated addition of 7 to the number 3, define `g(x) = x + 7`, then `Iteration(g, 3, 4)` yields (((3+7) +7) +7) +7 = 31.

Iteration( <Expression>, <Variable Name>, ..., <Start Values>, <Number of Iterations> )
Iterates the expression n times (n = number of iterations) using the given start value. The result is then the last element of the output of IterationList Command, with the same parameters.
Example: :`Iteration(a^2+1,a,{(1+ί)/(sqrt(2))},5)` will do a repeated iteration on a complex number
Note: See IterationList Command for further details.
