I have a complex valued matrix im_dc (512*512 size) out of which I want to display the absolute valued matrix as a figure. I used

figure(100), imshow(abs(im_dc),[]);drawnow;

which displays the image correctly. Now the issue is that i want to save this particular image as a jpg, run a loop 500 times (i will vary some parameters for every instance of the loop) which will give me 500 such im_dc images and then create a database out of all these. Can anyone help me with the coding?

在 MATLAB Online 中打开

 for k=1:500
   %do the operation as per your proposed work
   %k=final_resultant image_which you want to save 
   destination='complete path\im'; % Save image name as im1,im2...im500 
   % Complete path of the folder, where you want to save the images
   imwrite(k,[destination,num2str(k),'.jpg']); 
 end
