(* Dear friends, I wish build a package where the user, as one option,
can be choose one of three methods of evaluation, i.e: Automatic, LT or
EV. Some thing like this silly example *)
BeginPackage["test`test`"]
methodTest::usage="methodTest. This is an example"
Options[methodTest]={Method\[Rule]Automatic};
Begin["`Private`"]
methodTest[matrixA_, incond_, opts___]:=
If[Automatic == Method/.{opts}/.Options[methodTest],
Module[{a, b, r},(a = matrixA; b = incond; r = a b)]]
methodTest[matrixA_, incond_, opts___]:=
If[LT == Method/.{opts}/.Options[methodTest],
Module[{a, b, r},(a = matrixA; b = incond; r = a /b)]]
methodTest[matrixA_, incond_, opts___]:=
If[EV == Method/.{opts}/.Options[methodTest],
Module[{a, b, r},(a = matrixA; b = incond; r = a + b)]]
End[]
Protect[methodTest];
EndPackage[]
list1 ={{a11, a12 },{a21,a22}}
methodTest[list1,list2]
methodTest[list1,list2, Method\[Rule]EV]
methodTest[list1,list2, Method\[Rule]LT]
(*How can I get that this example work?*)
