Too many input arguments for Max function in 2018b

Hi all,

I am using the function 'max' in its newest format for 2018b, as shown here, and I have the following code:

A = randi(361,15) ; 
[E, i] = max(A, [], 'all', 'linear', 'omitnan') ;

However I am getting the error

Error using max
Too many input arguments.

The weird thing is that the above script works perfectly for my work computer with MATLAB 2019b. However in the current computer that I am using which has the 2018b version (which according to the mathworks website is supposed to support this format of the max function), it appears not to work. Any ideas as to why?

KR,

P.S. Here are the details for the MATLAB installed in the computer that returs the aforementioned error:

The linear option in r2019b [M,I] = max(A,[],___,'linear') was not included in r2018b.

For r2018b you can use,

[E, i] = max(A(:), [], 'omitnan') ;

instead of

[E, i] = max(A, [], 'all', 'linear', 'omitnan') ;

[KostasK]

Alright I see, in which case does the index i that is returned from the 2019b function is the same as that of the 2018b?

[Adam Danz]

Yes, these lines are equivilant. You could test that by entering a small matrix such as

A = magic(5);

Thanks!
