String theory tries to bring relativity and quantum physics into one general theory of everything. Learn about string theory in this article. Advertisement Pull a loose thread on a...@William: Please post the input data such that we can know the class and the size. Currently it is not clear, if your data are a double vector, a cell vector or any equivalent data also.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.9. You have a cell array of char, not strings. string and char mean different things since the release of R2016b. You can prepend a char array to a cell array in the same way how cell arrays are combined. In the similar way, you can also combine a cell array of char with a string array or a simple char array with a string array which will ...

Even if I replace the empty cells with "", it still gives an error: CELL2MAT ...Description. example. A = cell2mat(C) converts a cell array into an ordinary array. The elements of the cell array must all contain the same data type, and the resulting array is of that data type. The contents of C must support concatenation into an N-dimensional rectangle. Otherwise, the results are undefined.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.Sure you can hang clothes on the shower rod or be content with a simple drying rack in the laundry room.

When you use cell arrays, you give up the performance advantages that come from using string arrays. And in fact, most functions do not accept cell arrays of strings as input arguments, options, or values of name-value pairs.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". For more information, see Access Data in Cell ...Creation. You can create a string scalar by enclosing a piece of text in double quotes. str = "Hello, world". str =. "Hello, world". To create a string array, you can concatenate string scalars using square brackets, just as you can concatenate numbers into a numeric array. str = [ "Mercury" "Gemini" "Apollo" ;
