Use the pulsewidth function with the argument MidPercentReferenceLevel set to 0 or 1 (the lowest value). Here is an example:
x = 1:50;
y = zeros(size(x));
y(33:35) = 1;
width = round(pulsewidth(y,1,'MidPercentReferenceLevel',1,'Tolerance',0.1));
width =
4
Or, using your data:
H = openfig('Query.fig');
C = get(H,'Children');
x = C(4).XData;
y = C(4).YData;
width = round(pulsewidth(y,1,'MidPercentReferenceLevel',1,'Tolerance',0.1))
width =
4 5 6 5
Alternatively, if your data contains only ones and zeros:
start1 = strfind([0,y],[0 1]);
end1 = strfind([y,0],[1 0]);
width = end1-start1+2
width =
4 5 6 5
