how to concatenate image variable

Hi,

I have a sequence of images such as - img1,img2...img10 and I need to send them to a function as images via loop. If I use the following code rows, I get vector that include a string variables (like 'img1', 'img2'...) and I can't send them to the function as image:

for i=1:10
    Img(i)=['img',num2str(i)];
end

How can I define a vector of these images as a variables not as string for sending them through the function?

Thanks, Itai

Put the images into one array, e.g. a cell array or an ND numeric array. Then your task is trivial to achieve using simple, very efficient indexing.

Whatever you do, do NOT try to magically access variable names in a loop: this will make your code slow, complex, buggy, obfuscated, and hard to debug. Read this to know more:

YOu can get all the images present in the folder using:

img = dir('*.jpg') ;   % give your extension

for i = 1:length(img)
    img(i).name
end
