  1. I have 3 subplots in the format (3,1,1),(3,1,2),(3,1,3) and I want to add a common legend on top of these plots. How do I do that?
  2. How to add a title where I have a string and 3 numeric value I would like to take as input. It prints multiple times with my current code
A = 25
B = 0.02
C = 0.09
D = plaintext(E)% E might contain _ values
title(sprintf('D: %g A=%.2f, B=%.3f, C=%.3f',plaintext(E),A,B,C))
function s = plaintext( s )
s = regexprep( s, '[\\\^\_]','\\$0');
end

Basically, I am trying to add a legend on top of the first subplot which will be generic like has shapes and the corresponding names with some color coding. Not trying to pull anything specific from the subplots. Is it possible then?

Legend positioning is possible for subplots using that custom function. Have a look at it. Otherwise you need an extra subplot to display legend something like what @starstrider demonstrated.
