How to reorganization all image long z axis

Dear all, I have a question and would like to seek your help. There are beam signals. I took several 2D images (x,y) along the z axis, and I would like to reorganise all images along the z axis. Could you please give me some help? (a few images has attached) I would like to combine with 1.5.bmp, 2.0.bmp, 2.5.bmp along the z-axis . Thank you very much : )

What do you mean by reorganise? You want to plot them?

[Tina Hsiao]

yes! I would like to plot them along z axis.

[Tina Hsiao]

x and y data is from image, z data is from file name. For example: z= 1.5 mm, the x,y data from the image 1.5.bmp ; z = 2.0mm. the x1,y1, data from the image 2.0.bmp, etc...

slice and sliceViewer may also come in handy, although they don't produce the results you're describing above.

files = dir('*.bmp');

full_file_names = fullfile({files.folder},{files.name});
[~,fn,~] = fileparts(full_file_names);
z = str2double(fn);

figure
hold on

for ii = 1:numel(files)
    [I,map] = imread(full_file_names{ii});
    warp(z(ii)*ones(size(I)),I,map);
end

xlabel('x')
ylabel('y')
zlabel('z')

Thank you for the help, but I am sorry, I still can not plot the figure successfully. My code is below, thanks for helping me again.

clear all; close all; clc

D= '/Users/Tina/Desktop/2022.06.30';
S= dir(fullfile(D,'*.bmp'));
% files = dir('*.bmp');
full_file_names = fullfile({files.folder},{files.name});
[~,fn,~] = fileparts(full_file_names);
z = str2double(fn)

figure
hold on

for ii = 1:numel(files)
    [I,map] = imread(full_file_names{ii});
    warp(z(ii)*ones(size(I)),I,map);
end

xlabel('x')
ylabel('y')
zlabel('z')

[Voss]

The variable returned from dir is called files in my example, not S:

clear all; close all; clc

D= '/Users/Tina/Desktop/2022.06.30';

% S= dir(fullfile(D,'*.bmp'));
files = dir(fullfile(D,'*.bmp'));

full_file_names = fullfile({files.folder},{files.name});
[~,fn,~] = fileparts(full_file_names);
z = str2double(fn)

figure
hold on

for ii = 1:numel(files)
    [I,map] = imread(full_file_names{ii});
    warp(z(ii)*ones(size(I)),I,map);
end

xlabel('x')
ylabel('y')
zlabel('z')

I am sorry again! I follow your suggestion, but I still get error which shows as below, could you please help me again? Thanks a lot. My matlab version is R2017a

Error using fileparts (line 32)

Input must be a row vector of characters.

[Voss]

OK, try this:

clear all; close all; clc

D= '/Users/Tina/Desktop/2022.06.30';

files = dir(fullfile(D,'*.bmp'))

figure
hold on

for ii = 1:numel(files)
    full_file_name = fullfile(D,files(ii).name);
    [~,fn,~] = fileparts(full_file_name);
    z = str2double(fn);
    [I,map] = imread(full_file_name);
    warp(z*ones(size(I)),I,map);
end

xlabel('x')
ylabel('y')
zlabel('z')

Thank you very much for your help. It works well : )

You're welcome! I'm glad it's working!
