How to write the name of file into entry of matrices?

I want to write the name of some pictures as a entry of a matrices

i have code like this:

myFolder = uigetdir;
filePattern = fullfile(myFolder, '*.jpg');
theFiles = dir(filePattern);
BanyakGambar=length(theFiles)
for k = 1 : BanyakGambar
    baseFileName = theFiles(k).name;
    fullFileName = fullfile(theFiles(k).folder, baseFileName);
    fprintf(1, 'running %s\n', baseFileName);
    D(k,1)=k;
    s=string(baseFileName);
    D(k,2)=s;  %This line is the problem!! 
end

but why the name of the pictures can't display in matrices D, and i got this result for matrices D

i expect the result is like this (manually write in excel). Thankyou in advance

Yes, he is my lecturer

[Walter Roberson]

Lecturers should not need to post requests for help in solving an assignment.

And I do mean word for word identical. Except for the final "thank you". Not just the problem set, but identical words of description.

You cannot do that. It is never possible to store a string() or character vector into a numeric object.

You need to use a cell array or struct or table()

[Frisda Sianipar]

Can you give some example to do that sir?

[Walter Roberson]

word = {'hello'; 'Frisda'}

word = 2×1 cell array
    {'hello' }
    {'Frisda'}

number = [86; 99]

number = 2×1

86 99

as_cell = [word,  num2cell(number)]

as_cell = 2×2 cell array
    {'hello' }    {[86]}
    {'Frisda'}    {[99]}

as_table = table(word, number)

as_table = 2×2 table
       word       number
    __________    ______

    {'hello' }      86  
    {'Frisda'}      99  

as_struct = struct('word', word, 'number', number)

as_struct = 2×1 struct array with fields:
    word
    number
