    %% Set Data Type Override on a fi Object  
% Set the |DataTypeOverride| property of a |fi| object so that the |fi|
% object does not use the data type override settings of the |fipref| object.   

%% 
% Set up |fipref| with data type override set to |'TrueDoubles'| for all
% numeric types. 
fipref('DataTypeOverride', 'TrueDoubles')  

%% 
% Create a new |fi| object without specifying its |DataTypeOverride| property
% so that it uses the data type override settings specified using |fipref|. 
x = fi(pi, 1, 16, 13)  

%% 
% Now create a |fi| object and set its |DataTypeOverride| property to |'Off'|
% so that it ignores the data type override settings specified using |fipref|. 
y = fi(pi, 1, 16, 13, 'DataTypeOverride','Off')
