MATLAB: How to creat a empty string

Question

Hi,

I need to add string to a string array, but I cannot get the results with length of 3 (like the matrix in the following code), but 4 with a empty string("") for first element. How can I create a empty string? or any alternertive approach for this purpose? Thank you very much

Example:

% for matrix
a = [];
for i = 1:3
    a(end+1) = 1;
end

results: a = 1 1 1

% for string
a = string(); % a = strings; a = ""; works same
for i = 1:3
    a(end+1) = "1";
end

results: a =

1×4 string array

"" "1" "1" "1"

Answer 1

% for string
a = string([]);
for i = 1:3
    a(end+1) = "1";
end
