When i plot a grayscale image and check the value of a pixel using data cursor, it shows me the values between 0 and 1 which looks reasonable but it has a RGB scale. Can a grayscale image has RGB Values ?
x = rand([100 50]); i = mat2gray(x); imshow(i)

Hi, I want a 2d array of rows and columns filled with floating point numbers (matrix) which can be converted to a grayscale image.
Should i use the mat2gray function of matlab ? I want to program my own image and fill it with numbers.
