When I type into command window, license('test', 'image_toolbox'), it returns 1.
My code reads and displays images by imread, imshow. But it when I use mat2gray in the next line, there's an error "'mat2gray' requires Image Processing Toolbox."

You have the Image Processing Toolbox licensed but you do not have it installed

Either reinstall the complete MATLAB, or use the Add-ons/Get Add ons button on the Home tab of the tool ribbon to install just the Image Processing Toolbox.
