Reading images from file in MATLAB

I have bmp images in image folder on my computer. I named it from 1.bmp to 100.bmp.

And I want to read these images like this:

for i=1:100
    s='C:\images'+i+'.bmp';
    A=imread(s);
end

But Matlab gave an error. How can I implement this?

here i am using num2str which is used for convert the data type of number to string and i am using try for aviod the error because if file is not there then it will aviod that error.

Add your folder to the matlab directory path and run the following commands.

files=dir('*.bmp') for k=1:numel(files) I=imread(files(k).name); end

I am using these commands to read the image files.

imgfiles=dir('c:\images\*.*');
for k=1:length(imgfiles)
  ...
end

Create s in the following way:

s = ['C:\images\' int2str(i) '.bmp'];

Also, your loop will simply keep overwriting A, so you will instead have to make it a cell array to store all 100 images. Do this outside your loop:

A = cell(1,100);

and then load your images in the loop like so:

A{i} = imread(s);

You can use sprintf function

s = sprintf('c:\images%d.bmp', i);
A = imread(s);

let me guess. you don't have files named C:\images1.bmp. Oh, that's not the error you're getting, but it will be the next one, once you follow ypnos's advice.
