- 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^2the commandIteration(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, thenIteration(g, 3, 4)yields (((3+7) +7) +7) +7 = 31.
- After defining
- 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.
