How to open a number of directories equal to a number given by a user

Im trying to open tif images from a number of directories given by the user in a inputdlg. Afterwards im trying to plot these tif images as a figure. What I cant figure out is how to get a new directory to open for each iteration of the for loop. Any help is appreciated, below is my code:

answer = inputdlg('Enter Number:');
value = str2double(answer{1});

for k = 1:numel(value)
    P = uigetdir('C:\');
    S = dir(fullfile(P(k),"*.tif"));
    F = fullfile(S(k).folder,S(k).name);
    [A, R, cmap] = readgeoraster(F(k));

    figure
    mapshow(A, cmap, R)
end

P is not a vector so you do not need to index it. Its value is updated each loop. Just use it as you would outside a loop.

This is also true for S and F.

Also, how many numbers do you expect people to enter? I assume just one. Your code will loop numel(value) times, which should be once. I think you want it to loop value times.

Try this. Note this assumes one tif file per directory. If there are more, you will need a second for loop to load the images one at a time.

answer = inputdlg('Enter Number:');
value = str2double(answer{1});

for k = 1:value
    P = uigetdir('C:\');
    S = dir(fullfile(P,"*.tif"));
    F = fullfile(S.folder,S.name);
    [A, R, cmap] = readgeoraster(F);

    figure
    mapshow(A, cmap, R)
end

The user might enter a 1 or values greater than that, for this specific tool I would guess 3 to 5 would be the number they would want to enter. Your code worked! thank you for your answer.
