Unstacking table or timetable variables is not supported. Use SPLITVARS to split ''{0}'' into multiple variables. The indicator variable must be specified as a single variable. The indicator variable cannot be a pattern. The aggregation function must be specified as a function handle. The grouping variables and the data variables must not have variables in common. The indicator variable must not be a grouping variable or a data variable. A constant variable must not be the indicator variable, a data variable, or a grouping variable. UNIQUE returned a non-scalar value when used as the default aggregation function. Specify an aggregation function that returns a scalar value. The aggregation function must always return a scalar value, even when a group in the input table has zero or multiple rows for a given value of the indicator variable. The aggregation function must return a value whose size conforms to elements of the data variable ''{0}''. The names supplied for the unstacked data variables in the result conflict with other variable names in the result. The aggregation function must return a numeric or logical value that can be cast to the class of the data variable ''{0}''. Error when assigning output of aggregation function to table variable ''{0}''. Unstacking table row names is not supported. Create a table containing those row names as a variable. Unstacking table using row names as the indicator variable is not supported. Create a table containing those row names as a variable. When a group has no rows for a given value of the indicator variable, UNSTACK calls the supplied aggregation function with an input of size 0-by-1 instead of automatically filling the value. Review the output to ensure desired result is obtained. This warning might be removed in a future release. There are {0} unique values in the indicator variable. Specify {0} variable names using the NEWDATAVARIABLENAMES name-value pair. New data variable names should be empty when there are no variables to unstack. When generating code, new data variable names must be specified. Data variables must be constant. Indicator variable must be constant. Grouping variables must be constant. Constant variables must be constant. New data variable names must be constant. Aggregation function must be constant. The number of new data variable names must be equal to the number of unique values in the indicator variable. For code generation, the default aggregation function does not support cell array inputs. Specify a different aggregation function.
