Create an array of empty strings that is the same size as an existing array. A = [1 2 3; 4 5 6];
To create empty arrays that work with text as data, use the strings function. This function creates a string array of any specified size with no characters. For example, create a 0-by-5 empty string array.
Create an empty string array using the strings function. When you call strings with no arguments, it returns an empty string. Note that the size of str is 1-by-1, not 0-by-0.
The cell array created by cell(n,m) contains empty matrices, not doubles. If you really need to pre populate your cell array with empty strings test = cell(n,m); test(:) = {''}; test(1,:) = {'1st row'}; test(:,1) = {'1st col'};
Assuming you want to preallocate the length of x, you can assign a character to an element in x directly: % Preallocate x. x = repmat(char(0),1,10); % Assign a character to x. x(1) = 'A'; Where you can replace the 1 with any element in the array.
Each element of a character array stores only one character, so (until the string class was introduced) the only way to store multiple characters using a scalar index (as the question poses) is to use a cell array.
How do I append a string to a Matlab array column wise? Here is a small code snippet of what I am trying to do: for_loop filename = 'string'; name=[name; filename] end
Test for Empty Strings. You can test a string array for empty strings using the == operator. You can create an empty string using double quotes with nothing between them (""). Note that the size of str is 1-by-1, not 0-by-0. However, str contains zero characters.
If A is empty, [], the output is a 0-by-0 empty string array. Use char, ' ' to convert to ASCII or Unicode points.
You can expand an empty array into a nonempty array by assigning a specific value into the empty array. Any object you assign to the array must be of the same class or convertible to the class of the empty array. For example, create an empty array of uint8 and try to assign a string value to it.
