I am calculating incomplete gamma function using gammainc gammainc(0.04344,0,'upper') and I get the result as zero
but when I calculate same integral numerically I get result 2.6. I have also verified this results with other software, which gives the same result.
for example (using MuPAD)
double(feval(symengine,'igamma', 0, 0.043444))
gives me the result 2.6
Why I am not able to get same result with gammainc…
