Image conversion functions rgb2gray and im2double, no longer
requiring Image Processing Toolbox
MATLAB now includes the rgb2gray and im2double functions, which previously required
the Image Processing Toolbox™. Use rgb2gray to convert RGB images or colormaps to
grayscale. Use im2double to convert an image to double-precision values.
imshow function for displaying images from matrices or files, no longer
requiring Image Processing Toolbox
MATLAB now includes the imshow function, which previously required the Image
Processing Toolbox. Use imshow to display images from matrices or files.
