i wanted to implement mean shift filter on a 1 dimensional array data (sampled noisy square output from DAQ).
Pls find the attached file 'testdata' which has the data required for filtering.
Can any one help me in this regard?

You can just do
x = detrend(testdata,0);
Now compare:
subplot(211)
plot(testdata)
subplot(212)
plot(x)

Shailendra, there is a function in the Signal Processing Toolbox peak2peak that will do that.
You do have some noise in your data so simply mean shifting the data will not get rid of that problem.
I recommend peak2peak() if you have access to it.
Otherwise, you're going to have do some lowpass filtering and then peak detection.
