- 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 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.
Note: See IterationList Command for further details.
