I have got a grayscale image and i want to find its magnitude. As in that image should return a single scalar number.

What do you mean by the magnitude of a grayscale image? Do you want the average pixel intensity, or do you want the total pixel intensity, or something else? And are you trying to do this in Simulink or in MATLAB?
Total intensity:
sum(YourImage(:))
Average intensity:
mean(YourImage(:))
