given: a signal as a time series
return: discrete number of times is is holds a nonzero position
For example:
given: [0,1,0.5,0.7,0,1]
return: 2
given: [0,1,0,0,0,.3,1,0,0,1]
return: 3
given: [0,1]
return: 1
is there a way to do this task in a vector manner as opposed to a for loop that counts nonzero periods as it encounters them and flicks a counter.

a=[0,1,0,0,0,.3,1,0,0,1]
out=numel(strfind([0 logical(a)],[0 1]))
