I am trying to save a figure I have to the workspace. The current workflow involves using the print function and then reopen it using imread. Is there a way to jump over the print + imread functions and just save the image to a variable in the workspace? I need to save it with a certain resolution (1024x1024 pixels)
print('MoonImage','-dpng','-r300')

You can use the following lines of code to save the figure to workspace and set the desired resolution:
f= frame2im(getframe(gcf));
I=imresize(f,[1024,1024]);
For more information on the ‘gcf’ function, refer the following link:
