Follow-up Comment #6, bug #55059 (project octave):
I took a look at this tests and found that we are not Matlab compatible.
Consider this minimal example:
>> A = grayslice (uint8([0 100 200 255]), [.1 .4 .5])
A =
1x4 uint8 row vector
0 3 3 3
>> A = grayslice (uint8([0 100 200 255]), [100 199 200 210])
A =
1x4 uint8 row vector
0 1 3 4
The Matlab documentation states that V is always in the [0 1] range and is
converted internally for the type of the image but that does not seem to be
happening. Can anyone comment?
I get that Matlab documentation is not always right but this is so
outrageously wrong that I may be missing something.
In the mean time, I added a bunch of new tests for corner cases.
