As to indexing () vs {}: () returns a portion of the cell array. It always output a cell array, even if you only ask for one cell. You use this when you want to manipulate the container and don't care about what's in the cells.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 ...Copy. strjoin (A) will create a character array.

Use a numeric double to specify dim. To create a structure array with fields derived from N rows of a cell array, specify N field names in the fields argument, and the number 1 in the dim argument. To create a structure array with fields ...2. No, there is no such function. I ran into similar problems, so here is a very rudimentary function that I use. Do realize that it is not complete. For example, it does not output fields of a structure in a meaningful way, but that can easily be added. You can treat it as a base implementation and fit it to your needs.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 ...I first created two large cell arrays: a = cellstr(num2str((1:10000).')); %'# A cell array with 10,000 strings b = cellstr(num2str((1:10001).')); %'# A cell array with 10,001 strings Next, I ran each solution 100 times over to get a mean execution time. Then, I swapped a and b and reran it. Here are the results: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);0. A really simple way if you don't want to mess with automation: Double click on the variable in the workspace. In the Variables window click on the top-left box to select the entire cell array. Right-click -> copy. Paste to wherever you like! I have tested this with R2012b in Linux with Libre Office. It should work with Excel as well.Description. example.
