Method

Method

is an option for various algorithm-intensive functions that specifies what internal methods they should use.

Details

  • Typical settings include:
  • Automaticpick the method automatically
    "name"use the method with the specified name
    {"name",opt1->val1,}use the specified method with particular options
    {"name1",Method->{"name2",}}use a method and a submethod
    {opt1->val1,opt2->val2,}give options for methods
  • With the default setting Method->Automatic, the Wolfram Language will automatically try to pick the best method for a particular computation.
