It supports empties, logicals, chars, function handles, numerics, cells, struct (arrays), and user-defined classes (sparse arrays in the next update).To make your code accept cell arrays and structures that contain strings as input arguments, add a call to convertContainedStringsToChars to the beginning of your code. …Update code that makes use of strjoin to use join instead. strjoin returns a character vector if the input is a cell array of character vectors and returns a string scalar if the input is a string array. join returns a text scalar of the same type as the input. For example: 'one two three'. {'one two three'} 'one two three'.str = append(str1, ' ' ,str2) str =. "Good Morning". As an alternative, you can use the plus operator to combine strings. str = str1 + ' ' + str2. str =. "Good Morning". However, the best practice is to use append when you do not know whether the input arguments are strings, character vectors, or cell arrays of character vectors.Dec 9, 2013 · y{1}(2) ans =. G. Also keep in mind that the char function can convert a cell array of strings into a 2D character array by vertically concatenating the strings while padding with white space as necessary: S = char(C), when C is a cell array of strings, places each element of C into the rows of the character array S. Use CELLSTR to convert back. and so on. Why? Apparently this code tries to concatenate a nested cell array to a string (a cell array containing a matrix of chars which constitute the string like 'banana'). So, correct answer is. Use {:} for fruit = fruits [fruit{:} 'is a fruit'] end Magically this already produces the expected 'banana is a fruit', 'apple is a fruit', etc ...
