Asking for help, clarification, or responding to other answers. To pass data from a string array to such functions, use the cellstr function to convert the string array to a cell array of character vectors. In the context of matrix vectorization, using linear indexing with sub2ind and ind2sub are extremely useful, however, there is no such thing for cell array.
