imread with new name

I want to pre-load images before displaying them later. In order to do so, I need to save them with different names. Here is the code to loop through the folder of images:

for i=1:50

Names=imageNames{i};

Number=num2str(i);

NewName=strcat('ImageID_','Number);

NewName=imread(Names);

end;

But, I'd like the images to be saved as a variable string (e.g., "ImageID_1", "ImageID_2", etc.) but it is instead saving the image as "NewName"

"I'd like the images to be saved as a variable string (e.g., "ImageID_1", "ImageID_2", etc.)"

And force yourself into writing slow, complex, inefficent code that you would need to access those variable names:

The simple, efficient, recommended solution is to use indexing into one array (e.g. a cell array), just as the documentation shows:

Instead of 50 different variables named ImageID_1, ImageID_2, etc., how about one variable (a cell array) that contains all 50 images?

n_images = numel(imageNames);
Images = cell(1,n_images);
for ii = 1:n_images
    Images{ii} = imread(imageNames{ii});
end

Then you can access any image by indexing into Images. For example, to get the 10th image:

Images{10}
