I don't know, if you really want to replace the values or create a new array of the same size with the strings in it. As the others pointed out, you need a cell array to store the strings. a = [1 1 1; 2 2 1; 3 3 2; 4 5 1]; aStrings = cell(3,4) aStrings(a==1) = {'apples'}k = strfind (str,pat) searches str for occurrences of pat. The output, k, indicates the starting index of each occurrence of pat in str. If pat is not found, then strfind returns an empty array, []. The strfind function executes a case-sensitive search. If str is a character vector or a string scalar, then strfind returns a vector of type double. Nov 16, 2014 · Sorry I should of been more clear with my first question as I ultimately wanted the output from the array a to be a string '12345' so I could put it into a position of another array.

OK so I have two lists of, say, names, List_one and List_two. - List_one is smaller than List_two: they are both cell arrays.To enable code that works with strings to accept character arrays as inputs, add a call to convertCharsToStrings 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 convertCharsToStrings . Strings in MATLAB are an array of characters. To see this, executing the following code: >> fstring = 'hello'; >> class (fstring) ans = char. Because strings are arrays, many array manipulation functions work including: size, transpose, and so on. Strings may be indexed to access specific elements.Parse a cell array of strings without looping. I've got a nx1 cell array of strings that correspond to spatial coordinates.
