Follow-up Comment #4, bug #50257 (group octave):

Running the commands:

img = uint8([1 2 3 4; 5 6 7 8; 9 10 11 12; 13 14 15 16]);
result = imtranslate(img, [0.3, 1.7], "cubic")

On 11.1.0 I get:

result =

   0   0   0   0
   0   0   1   1
   1   3   4   5
   5   7   8  10


On 7.2.0 I get:

result =

  0  0  0  0
  0  0  0  1
  1  3  4  5
  5  7  8  9

The cause of the difference is a change in interp2
