Debugging: creating a line with empty data
In this video we are sorting through some data making a different line for all the data points that match certain criteria. At some point in the algorithm none of the data meets the criteria. This is the equivalent of this:
>> a = 1
a =
1
>> a(2) = line([],[],[])
Improper assignment with rectangular empty matrix.
We figure out how to deal with this with a simple check around the line command.
