A duration display format must be a character vector or string scalar. The format ''{0}'' is not valid. Input data must be numeric, or a cell or string array containing duration text. Numeric input data must be a matrix with three columns, or else three or four separate numeric arrays. You can also create durations from a single numeric array using the YEARS, DAYS, HOURS, MINUTES, or SECONDS functions. Numeric input data arrays must be equal sizes, or any of them can be a scalar. Numeric input data must be real. DIM must be a positive integer value. Input data must be a real, numeric array, or a duration array. Use CALYEARS to extract whole calendar year numbers from a calendarDuration array. Input data must be a real, numeric array, or a duration array. Use CALDAYS to extract whole calendar day numbers from a calendarDuration array. Input data must be a real, numeric array, or a duration array. Use TIME or SPLIT to extract durations from a calendarDuration array. Input data must be a real, numeric array, or a duration array. Use YEAR to extract year numbers from a datetime array. Input data must be a real, numeric array, or a duration array. Use DAY to extract day numbers from a datetime array. Input data must be a real, numeric array, or a duration array. Use HOUR to extract hour numbers from a datetime array. Input data must be a real, numeric array, or a duration array. Use MINUTE to extract minute numbers from a datetime array. Input data must be a real, numeric array, or a duration array. Use SECOND to extract second numbers from a datetime array. Input data must be a real, numeric array, or a duration array. Undefined function ''{0}'' for input arguments of type 'duration'. To convert from durations to numeric, use the SECONDS, MINUTES, HOURS, DAYS, or YEARS functions. Undefined function ''{0}'' for input arguments of type 'duration'. Durations cannot represent calendar months. Use calendar durations instead.\n\nFor example, to find the difference between two datetimes in units of calendar months, use the BETWEEN function instead of subtraction. Cell contents reference from a non-cell array. Cell contents assignment to a non-cell array. Unrecognized property: ''{0}''. Invalid property name. ()-indexing may not be followed by () or '{}' in an index expression. You may not assign to the ''{0}'' property of the elements of a duration array. Use d.{0} = ... instead. Invalid LHS for assignment from a {0} array. Right hand side of an assignment must be a duration array, numeric array representing days, or text representing durations in timer formats (e.g. 'hh:mm:ss'). Unrecognized duration property ''{0}''. If you intended to call the {1} method, you must use a functional syntax such as {1}(d,...). See <a href="matlab:helpview(fullfile(docroot,'matlab/matlab_oop/method-invocation.html'))">Method Invocation</a> for more information. Unrecognized duration property ''{0}''. If you intended to call the {1} method, you must use a functional syntax. See <a href="matlab:helpview(fullfile(docroot,'matlab/matlab_oop/method-invocation.html'))">Method Invocation</a> for more information. Comparison is not defined between {0} and {1} arrays. Addition is not defined between {0} and {1} arrays. Subtraction is not defined between {0} and {1} arrays. Multiplication is not defined between two duration arrays. Multiplication is not defined between {0} and {1} arrays. Cannot divide a {0} array by a duration array. Division is not defined between {0} and {1} arrays. The denominator in matrix division for duration arrays must be a real scalar double value. Unrecognized duration format. Could not recognize the format of {0}.\nExpected data of the form ''{1}'' or ''{2}''. The duration text format is ambiguous. Specify ''InputFormat'' with ''{0}'' or ''{1}''. Unable to parse {0} using the format ''{1}''. A duration InputFormat must be a character vector or string scalar. Unsupported format ''{0}''. See the documentation of ''InputFormat'' for valid formats. Unable to convert the text ''{0}'' to a duration value because its format was not recognized. The 'InputFormat' parameter has no affect when creating a duration array from non-text data. It will be ignored. duration text The {0} method is not supported for duration in code generation. Creating durations from text inputs is not supported in code generation. Conversion to duration from {0} is not possible. The milliseconds must always be a real value.
