Hi Edoardo,
The reason why your function ‘check_present’ is displaying wrong values is because ‘fixed.Interval()’ function only generates interval when 1st argument passed to this function is lower in range then the 2nd one.
For e.g. -> fixed.Interval(2,8) would produce interval with Left-End ‘2’ & Right-End ‘8’.
But in the case fixed.Interval(7,1) it would produce an empty interval.
And according to the data being used in your scripts there are certain instances where streams like 'Sin' = 390 & 'Sout' = 110 are generated. Hence in such cases function gives wrong output.
Here is a possible workaround to deal with such cases:
function check_present(obj)
%Loops through each interval
for i = 1:length(obj.intervals)
%Creating "present" and "present names"
present = [];
present_names = [];
for k = 1:length(obj.streams)
leftStr = min(obj.streams(k).Sin,obj.streams(k).Sout);
rightStr = max(obj.streams(k).Sin,obj.streams(k).Sout);
streamCur = fixed.Interval(leftStr,rightStr);
intervalCur = fixed.Interval(obj.intervals(i).Tlow, obj.intervals(i).Thigh,'()');
if overlaps(streamCur,intervalCur)
present = [present; obj.streams(k)];
present_names = [present_names; obj.streams(k).name];
end
end
obj.intervals(i).present = present;
obj.intervals(i).present_names = present_names;
end
end
