Follow-up Comment #2, bug #50238 (project octave):
The issue indeed seems to be with cumsum: by default, Octave performs the
operation as double while Matlab uses the same class as the input and does not
provide a mechanism to change this behavior:
++
>> a = uint8([150 150]);
>> sum(a)
ans =
300
>> sum(a,'native')
ans =
uint8
255
>> cumsum(a)
ans =
1×2 uint8 row vector
150 255
>> cumsum(a,'native')
Error using cumsum
Invalid option. Option must be 'forward', 'reverse', 'omitnan' or
'includenan'.
