Como uso o comando rand em uma matriz de uma imagem? Quero que o programa leia a imagem e desenhe alguns elementos dessa matriz.

Try something like this:
randomIndexes = randperm(numel(grayImage), numIndexes);
extractedPixels = grayImage(randomIndexes);
where grayImage is your grayscale image, and numIndexes is the number of pixels you want to extract from the full image.
