How can I 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)

you can't save numbers and strings on the same matrix, if you want to do that use a cell array. to achieve this use e.g.

D{k,1}=...

it is recommended to initialize the whole cell array before you assign values to the individual cells (using the cell() command)
