Direction must be ''ascend'' or ''descend'', or a string array or a cell array containing those directions. Direction must have one element for each variable you sort on. The input table does not contain row names, returning the input unsorted. Numeric variable indices must be either positive or negative integers. Sorting variable ''{0}'' has more than 2 dimensions. An error occurred when sorting the variable ''{0}'', whose type is ''{1}''. An error occurred when sorting rows of the variable ''{0}'', whose type is ''{1}''. In code generation, sorting variables must be specified as constant. Sortrows does not support multi-column cellstr variables in code generation. Sortrows only supports specifying direction for cellstr variables. Other parameters are not supported in code generation.
