Requires: | jdqr.m, ILU.m, Example1.m, Example2.m and Matlab Version 5.1. |
Function: | testA |
Description: | Contains some examples for using preconditioning in jdqr.m |
File: | Example1.m |
---|---|
Requires: | Matlab Version 5.1. |
Function: | out=Example1(v) |
Description: | Example of a function file for jdqr of a linear operator. out is the result of the operator applied to the vector v. |
File: | Example2.m |
---|---|
Requires: | Matlab Version 5.1. |
Function: | out=Example2(v,flag) |
Description: | Example of a function file for jdqr of a linear operator. out is the result of the operator applied to the vector v when applied with 1 input argument. If flag='dimension' then out is the dimension N. If flag='preconditioner' then out is the result of "a preconditioner". |
File: | ILU.m |
---|---|
Requires: | Matlab Version 5.1. |
Function: | out=ILU(v) |
Description: | Example of a function file for jdqr of a preconditioner. out is the result of the preconditioner applied to the vector v. |
