If statement gives wrong result

So I have the follwing Matlab code:
if isKey(containers.Map(str2, str),hasher("YR_.1EC9", 'Algorithm', 'SHA256'))
fprintf('no')
else
fprintf('You can use this name')
end
if I run it, it tells me
You can use this name>>
. But if I seperately excute :
isKey(containers.Map(str2, str),hasher("YR_.1EC9", 'Algorithm', 'SHA256'))
It tells me
ans =
logical
1
I'm so confused as if the logical statement is 1, shouldn't the if statement gives me 'no'?

If it is logical 1 then it should say No. But check while you run the code did you overwrite any variable such that answer is 1. You better run in debug mode and check,

Hi Xinjie,
There may be several reasons for this issue
1)For example if you wrote the code that is going to make changes to str2 variable after the if-else-end, this might change the output of the isKey function when you run it
2)if the hasher function output is not same when executing it multiple times with the same input
if above statements cannot resolve the issue, then try debugging using the breakpoints. We need some more information about the code in order to reproduce and further investigate the issue
