For example: a ...Or use a more efficient solution on this as suggested by @Luis -. split1 = regexp(str_cellarr, ':', 'split') After this you can employ two approaches. Approach #1. Convert to a 2 element cell array with each cell containing each "set" of strings separated by the delimiter ':' -. split1_2cols = mat2cell(vertcat(split1{:}),size(str_cellarr,1),[1 ...names(i) = 'string'; end. And here is how to dynamically expand the array without preallocation: names = strings(0); for i=1:10. names(end+1) = 'string'; end. (Of course if the strings are all the same or form a sequence with a pattern, there are better ways to create the array without a loop. A cell array is a data type with indexed data containers called cells, where each cell can contain any type of data. For example: 1×3 cell array. {[42]} {5×5 double} {["abcd"]} To access the contents of a cell, enclose indices in curly braces, such as c{1} to return 42 and c{3} to return "abcd".

If your original cell array contains strings of a fixed length, you can follow Dan's suggestion and convert the cell array into an array of strings (a matrix of characters), reshape it and extract the desired columns: MyArrayOfSubStrings =vertcat(CellArrayOfStrings{:}); MyArrayOfSubStrings = MyArrayOfSubStrings(:, 3:4);Accepted Answer. Azzi Abdelmalek on 1 Feb 2015. Vote. 64. Link. Edited: MathWorks Support Team on 3 Sep 2020. Open in MATLAB Online. To convert a cell …Cell arrays follow the same basic rules for expansion, concatenation, and deletion as other types of MATLAB® arrays. However, you can index into a cell array in two ways: with curly braces {} to access cell contents or with parentheses to refer to the cells themselves. Keep this distinction in mind when you add, delete, or combine cells in a cell array. 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.

@excaza I know, but, as I have written at the beginning of my answer, the motivation for using a separate function is that the mapping might become more complex than just strcmps.In that case it would be much easier to rewrite the one function rather than inventing a new way of how to do it with the whole arrays (which may become non-trivial).

Description. You can represent text in MATLAB ® using string arrays. Each element of a string array stores a sequence of characters.
