Difference between graythresh and multithresh for one value of threshold.

graythresh(I) and multithresh(I,1) gives me different values even if both are based on otsu's method of thresholding Why?

t1 = multithresh(I,1);
t2 = graythresh(I);
t1 is a LEVEL, which means is a number between 0 to 255.
t2 is same LEVEL that mapped in [0 1].
In other word:
t1 == uint8(256*t2)

I gave you an example for an 8-bit digital image.
Example: Check it for 'coins.png' image.
What kind of image that you use?

It's a complex image. For more information: https://www.imageeprocessing.com/2015/03/how-to-read-image-file-or-complex-image.html
I don't know about this kind of images.
