It actually is 2D. Each pixel is represented by three colour channels, which is where the third dimension arises. To convert it to a 2D matrix, use the rgb2gray function.

在 MATLAB Online 中打开

Or extract just one of the color channels.

% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);
greenChannel = rgbImage(:, :, 2);
blueChannel = rgbImage(:, :, 3);

Each one of those channel images is a grayscale (monochrome) image. Which you do just depends on what you plan on doing with the 2D gray scale image.
