onoffids2logical(on​OffIds, varargin)

Convert start and end ids of events to logical indicator array.

You are now following this Submission

This is a utility function to compute a logical indicator array from the start and end ids of events in an array, e.g. 4/5 & 7/10 -> 00011011110. This is can be used quickly extract the events by logical indexing. It is vectorized and thus is very fast even for large arrays.
This function is part of a set of functions to convert between logical and number indexing in arrays:
