Hi,

I have a short question, I am creating a string with a loop but I cannot remove the quotation marks " ".

here is my code

folder_name_dia = linspace(0.05,5,100); %  used to create an automatic string 
for p=1:length(folder_name_dia)
test{p} = "diam_" +folder_name_dia(p);
end
test = test';

Does any know how can i remove the quotation marrks " "

The quotation marks are not actually part of the string. It is just displayed that way. Plus, since you are using strings instead of character vectors, you don't need to put them in a cell array. You can use a string array (with regular parentheses instead of curly braces):

folder_name_dia = linspace(0.05,5,100); %  used to create an automatic string
for p = 1:length(folder_name_dia)
    test(p) = "diam_" + folder_name_dia(p);
end
test = test';
test(1) % this shows the quotation marks to give you an indication that this is a string
ans = "diam_0.05"
disp(test(1)) % this just shows the string itself which doesn't actually have any quotation marks
diam_0.05
