Try putting brackets around the numbers to make a numerical vector, and then assigning it to another numerical vector.
Nan not a number, nat not a time, undefined categorical elements, and values are considered to be unequal to other elements, as well as themselves. String arrays index in the same way as other matlab arrays. However, to access character vectors in a cell array, most code uses curly brace indexing. This includes the size and type of the variables in the matfile. Compare each element in two cell arrays of character vectors.
