Applying the function ''{0}'' to the variable ''{1}'' generated the following error:\n\n{2}\n The function ''{0}'' returned a non-scalar value when applied to the variable ''{1}''. The function ''{0}'' returned a value with a mismatched type ({1}, expected {2}) when applied to the variable ''{3}''. Unable to concatenate incompatible values returned by the function ''{0}'' when applied to groups in the variable ''{1}'':\n\n{2}\n First input must be a function handle. OUTPUTFORMAT must be one of the following: 'uniform', 'table', or 'cell'. INPUTVARIABLES must return a logical scalar. FUN returned a 1-by-M character vector. You must modify FUN to return a cell array of character vectors, or specify ''cell'' for the ''OutputFormat'' parameter. The function ''{0}'' returned values with more rows than the input timetable. varfun is unable to create new row times for those extra rows when the output format is 'timetable'. To return a table instead of a timetable, set 'OutputFormat' to 'table'. Row names are not supported as a data variable. Unrecognized variable name ''{0}''. You may have intended to access the row names, which are named ''{1}'' in this table. However, row names are not supported as a data variable. Applying the function ''{0}'' to the {1} group in the variable ''{2}'' generated the following error:\n\n{3}\n The function ''{0}'' returned a non-scalar value when applied to the {1} group in the variable ''{2}''. The function ''{0}'' returned a value with a mismatched type ({1}, expected {2}) when applied to the {3} group in the variable ''{4}''. The function ''{0}'' returned a value with a different number of rows when applied to the {1} group in the variable ''{2}''. FUN must be constant. Variable size tables or timetables are not supported for varfun. The value of ''{0}'' must be constant. When using a function handle to specify InputVariables, the output of the function must be constant. Error Handler is not supported for code generation. In code generation, OutputFormat 'cell' is not supported, if GroupingVariables are specified and the function returns a different type for each InputVariable.
