    %% Largest Element Involving |NaN|
% Create a vector and compute its maximum, excluding |NaN| values.

A = [1.77 -0.005 3.98 -2.95 NaN 0.34 NaN 0.19];
M = max(A,[],'omitnan')

%% 
% |max(A)| will also produce this result since |'omitnan'| is the default
% option. 

%%
% Use the |'includenan'| flag to return |NaN|.
M = max(A,[],'includenan')
