How can I save multiple pictures via imwrite with the same scale?

Right now imwrite "assumes that the dynamic range is [0,1] and automatically scales the data by 255" but I want every picture have the same scale to compare them.

If you have R2018a or later, you can use normalize() to rescale the data. Otherwise you can use mat2gray() to rescale data. Or just double() the data if it is not already double precision, and divide by the maximum value you want, and im2uint8() the result.

Thanks, I will try the mat2gray option
