Fourth argument, category names, must be a cell array whose length is equal to the number of bins, {0,number,integer}. Unable to create unique category names using the display format of the input argument. Specify category names or change the ''Format'' property of the input. Second argument, uniform bin size, must be a positive finite scalar duration, or can be one of: 'second', 'minute', 'hour', 'day', or 'year'. Second argument, bin edges, must be a duration vector with at least 2 elements. Second argument must be either a scalar integer, scalar duration, scalar string, or character vector. Second argument, bin edges, must be a sorted duration vector that does not contain NaNs. Third argument, bin values, must be a vector whose length is equal to the number of bins, {0,number,integer}. If the third argument, bin values, is of type {0}, then all of the input data must belong to a bin. First argument must be a duration array.
