How can I use the FINDPEAKS function in the Signal Processing Toolbox 6.8 (R2007b) to find flat peaks?
Show older comments
The FINDPEAKS function does not consider peak points to be valid unless they are strictly greater than the immediately neighboring points.
Reproduction Steps:
good = [ 1 2 3 4 5 6 7 6 5 4 3 2 1]; % peak at 7
findpeaks(good) % this will return a value of 7
bad = [ 1 2 3 4 5 6 6 5 4 3 2 1]; % adjacent peaks at 6
findpeaks(bad) % this will return null []
I would like to be able to find flat tops (where the peak value is repeated a few times) using the FINDPEAKS function.

The ability to find peaks where the peak value occurs more than once is not available with FINDPEAKS function in Signal Processing Toolbox 6.6 (R2007b).
There are no workarounds.
