ML does not allow floats, etc.

Old versions of Octave do.
New version of Octave gives errors.
Patch informs these errors.

How did you create it?

diff -u

New version done with:

hg clone
cp ~/octave/winter.m octave/scripts/image/.
hg -diff winter >winter3.patch

(file #51358)

Re comment #2: Which version of Octave do you use?

Fwiw, with Matlab R2021a:

>> winter(2.5)
Error using zeros
Size inputs must be integers.

Error in winter (line 27)
c = [zeros(m,1) r .5+(1-r)/2];

>> winter(2.5+3i)
Warning: Colon operands must be real scalars.
> In winter (line 26)

Error using zeros
Size vector must be a row vector with real elements.

Error in winter (line 27)
c = [zeros(m,1) r .5+(1-r)/2];


So the behavior we currently have in Octave seems to be compatible.

Image to show it working.

New version requires integer.

AFAICS the patch actually removes the tests ... (diff'ed in the wrong direction?)
Changing the '-' into'+' fixes that :-)

More serious is this:

***** test
 assert (winter (2.5), [0 0 1; 0 0.66667 0.66667], 1e-5)
!!!!! test failed
conversion of 2.5 to int64_t value failed

## (after commenting that out, the next test fails as well:)
>> test winter
***** test
 assert (winter(2.5+3i), [0 0 1; 0 0.13333 - 0.26667i 0.93333 + 0.13333i], 1e-5)
!!!!! test failed
conversion of 2.5 to int64_t value failed

(with Octave-7.0.0  dev version)
