    %% Use the colon Operator With Signed and Unsigned Operands
% 
a= fi(int8(-1));
b = uint8(255);
c = a:b;
len = c.WordLength
signedness = c.Signedness
%%
% The word length of |c| requires an additional bit to handle the
% intersection of the ranges of |int8| and |uint8|. The data type of |c| is
% signed because the operand |a| is signed.
