TF = isbetween (X, lower, upper) returns a logical array TF, the same size as the broadcast of its inputs, containing true where the element of X lies between the corresponding lower and upper bounds. lower and upper may each be a datetime array or a date/time character vector, string array, or cell array of character vectors, and either may be scalar to broadcast against X. The comparison is made on the absolute instant, so zoned inputs may be in different time zones. A Not-A-Time element in any input makes the corresponding result false.

TF = isbetween (X, lower, upper, intervalType) selects which endpoints are included. intervalType is 'closed' (the default, lower X upper), 'open' (both endpoints excluded), 'openleft' (exclude lower), or 'openright' (exclude upper).
