I want to know how to use subscript and superscript in matlab. For example
fprintf('The optimal dual variable values are \x03bb 1=%0.4f , \x03bb 2=%0.4f ,\x 03bb3=%0.4f \n', l1,l2,l3);
In above \x03bb is unicode for lambda.I want to use 1 2 3 as subscript to lambdas. How can I put subscript to a unicode in matlab

There is a very limited ability to do that. The ASCII codes for superscripts 1, 2, and 3 are 185, 178 and 179.
You can insert them directly into the format string, or do something like this:
l1 = 3; l2 = 5; l3 = 7;
fprintf('The optimal dual variable values are \x03bb%c=%0.4f , \x03bb%c=%0.4f ,\x03bb%c=%0.4f \n',[185 178 179; l1,l2,l3]);
producing:
The optimal dual variable values are λ¹=3.0000 , λ²=5.0000 ,λ³=7.0000
.

There are unicode subscript and superscript characters.
disp(char(8320:8329))
You can use these, provided the font contains the glyphs. There are no general options to insert formatting of the output text through fprintf, although many parts of Matlab allow LaTeX formatting.
