Matlab cell array to string array.

You can create string arrays to contain multiple pieces of text. However, you might need to use functions that accept cell arrays of character vectors as input arguments, and that do not accept string arrays. 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 ... To enable your existing code to accept string arrays as input, add a call to convertStringsToChars at the beginning of your code. For example, if you have defined a function myFunc that accepts three input arguments, process all three inputs using convertStringsToChars . I propose 5 additional solutions, three of which are 4-5x faster by than the solutions proposed so far. The lessons learned from this are: num2str is slow; cellfun and arrayfun can add significant overheadString arrays are supported throughout MATLAB and MathWorks® products. Functions that accept character arrays (and cell arrays of character vectors) as inputs also accept string arrays. Represent Text with Character Vectors. To store a 1-by-n sequence of characters as a character vector, using the char data type, enclose it in single quotes.

MATLAB provides a rich set of functions to work with string arrays. For example, you can use the split, join, and sort functions to rearrange the string array names so that the names are in alphabetical order by last name. Split names on the space characters. Splitting changes names from a 5-by-1 string array to a 5-by-2 array.
