I have a matrix of 73 rows andd 12 columns having different values to each cell. I want to assign if cell value=0.5 display "0, else if cell value >=0.5 display "+1" else cell value<=0.5 display "-1". I tried following, but gives only one value.1,1 cell value is -0.5438.
if B==0.5;
disp='0';
elseif B>=0.5;
disp='+1';
else
disp='-1'
end

If you want to change array values, why are you using disp()?
This will produce the output of the same size:
A = rand(4,3); % a test array
A(1) = 0.5 % make sure at least one is exactly 0.5
B = sign(A-0.5) % simple numeric output
If for some reason, you want a bunch of text output:
cmap = {'-1','0','+1'};
Btext = cmap(sign(A-0.5)+2) % cellchar output
