TF = isequaln (D1, D2) returns a logical scalar TF, which is true, if the duration arrays D1 and D2 contain the same values or corresponding missing elements, and false otherwise. Either D1 or D2 can also be specified as a character vector, a cell array of character vectors or a string array containing valid text duration representations.

TF = isequaln (D1, D2, …) returns a logical scalar TF, which is true, if all input arguments are equal under the assumption that missing elements are equal, and false otherwise.
