I saved the file location on the variable (1*815 cell array). I used the following code to read the image. But however I am getting out of Memory error in Windows 7, Matlab 2015 trail version

 for i=1:815
     ni(i)=imread(char(fullFileName(1,i)));
 end

Any help is appreciated

Thanks in Advance

在 MATLAB Online 中打开

 for K = 1:length(fullFileName)
     ni{K} = imread(fullFileName{K});
 end

If your images are large enough, you will run out of memory trying to store all of them in memory simultaneously. If so then be sure to use 64 bit MATLAB and increase your physical memory or your swap space (but swap space is slow!!!). Or reconsider your code to figure out whether you really need all of the images to be in memory at the same time.
