Hi Rajeev,
If you are using the function MWNumericArray() the following way, it should display the complete vector as [1.1, 2.2, 3.3] and not only the first element.
% Define your input array x
x = [1.1, 2.2, 3.3];
% Create a numeric array using MWNumericArray
y = MWNumericArray(x);
% Display the numeric array
disp(y);
Moreover, you can refer the below mentioned documentation for MWNumericArray():
Thank you,
