Here's what we mean when we say that a product "works with" string arrays as inputs: In fact, in a future release nearly all MathWorks® products will work with string arrays as inputs. Public Service Announcement!Ī few paragraphs ago, I said that "many" MATLAB functions now accept string arrays as inputs arguments. If you are looking for more examples using strings, see: Introducing String Arrays, Singing the Praises of Strings, and Working with Text in MATLAB.Īnd of course, you can find the documentation for string arrays at Characters and Strings. I won't belabor the point, because Loren already has published some wonderful guest posts on using string arrays. As you work with your text in a string array, you never have to resort to cell arrays or curly brace indexing. String arrays now provide a powerful way to deal with text in your data. Let's reshape it as a row vector of strings for more compact display. The split function returns the string array as a column vector. Instead of getting a cell array, you get a homogeneous array storing text-an array that has the same data type you started with. If you use the split function to split that string on space characters, then the result is a string array with nine elements. "A horse! a horse! My kingdom for a horse!" (Single-quotes still create a character vector.) str = "A horse! a horse! My kingdom for a horse!" str = As of R2017a, you can use double-quotes to create a string. Start with some text you can store as one string-or as a string scalar, a term we use to describe a string array with one element. Also, you can use many MATLAB functions (such as sort and unique) on string arrays. You can use standard array indexing and operations on string arrays, along with string manipulation functions introduced in R2016b. Each element of a string array stores a sequence of characters. In R2016b, MATLAB® introduced the string data type as a new data type for text. How to Make Your Code Work with Strings.
