Name:

infnorm computes an interval bounding the infinity norm of a function on an interval.

Usage:

infnorm(f,I,filename,Ilist) : (function, range, string, list) -> range

Parameters:

Description:

Example 1:

   > infnorm(exp(x),[-2;3]);
   [2.00855369231876677409285296545817178969879078385537e1;2.00855369231876677409285296545817178969879078385544e1]

Example 2:

   > infnorm(exp(x),[-2;3],"proof.txt");
   [2.00855369231876677409285296545817178969879078385537e1;2.00855369231876677409285296545817178969879078385544e1]

Example 3:

   > infnorm(exp(x),[-2;3],[| [0;1], [2;2.5] |]);
   [2.00855369231876677409285296545817178969879078385537e1;2.00855369231876677409285296545817178969879078385544e1]

Example 4:

   > infnorm(exp(x),[-2;3],"proof.txt", [| [0;1], [2;2.5] |]);
