First use
gray_image = rgb2gray(RGB_image);
The rescale the image:
B = imresize(gray_image, scale)
Take a look at
doc rgb2gray
doc imresize
The order of the operations can be reverse.

% Convert to grayscale.
grayImage = rgb2gray(rgbImage);
% Resize to 11*92 or 112*92 (whatever is wanted), if necessary.
grayImage = imresize(grayImage, [112, 92]);
% Convert to pgm format disk file
imwrite(grayImage, 'myFile.pgm');
