Hi. Please I need a help with the following,
if 4<A && A<5
display(' No value')
else
display(' There is a value')
end
if statement does not give the right values of A. Please any one can help me why it does not work properly?

If you have a vector in A, this is the wrong thing to do. An if statement does not apply to each element of a vector, independently.

Yes A is a vector. Please, how can I introduce "if" then?

To display the values you want write:
A(4<A&A<5)

I think what you want to do would be like this. BTW, display function is not recommended. Please use disp function instead.
% Sample data
A = 5*rand(10,1);
idx = (4 < A) & (A < 5);
for kk = 1:numel(idx)
if idx(kk)
disp('No value')
else
disp('There is a value')
end
end
