| Hi All,
|
| I have been using LinearFilter on my data with 
great success & achieve
| better results the more times I pass my data 
through the LinearFilter. (
| I have had to adjust data length to maintain 
correct indexing with
| PadLeft - but this is not my question here.)
|
| Below is how I am applying the multiple 
LinearFilter.
|
| EG
|
| originaldata
|
| Data1=LinearFilter[originaldata, {1/2,1/2}];
| Data2=LinearFilter[Data1, {1/2,1/2}];
| Data3=LinearFilter[Data2, {1/2,1/2}];
|
|
| My question is - Is there a shorter way of 
writing multiple passes of
| the above.
|
| If there is a way, please show the code.
|
| It would be great if I could simply adjust the 
number of passes from say
| three above to any number of passes to find 
optimum setting for data.
|
| Many thanks for your attention.
|
| Best Regards - Lea Rebanks...
