How to use M such that State_x iteratively gets the above values.

Kashif :
See the FAQ:
http://matlabwiki.mathworks.com/MATLAB_FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F

The recommended way is this:
State_1=State_{1} ;
State_2=State_{2};
State_3=State_{3};
especially when you only have a few variables.
Otherwise make an array
for M=1:3
NewState(M) = State_{M};
end

The answer is DON'T DO IT!

Use a cell array instead, or any array that is
appropriate. Preallocate your arrays when you
do this sort of thing if possible.

Generating long lists of numbered arrays in a
loop is a poor way to write code in general.

Thanks all for the help.
I guess I dint convey my point properly. My question was how to manipulate the variable name on each iteration. I guess some string operation are involved. Need help on that.

I do understand that I can do it as below plus I can also use arrays to assign values if there are large no of states.

State_1 = [10,20,30] ;

State_2 = [4] ;

States = {State_1,State_2}; % Structure

for M = 1: 2

State_X = States{M};

% Perform some operations on State_X
%...
%...
%Then Clear State_X

end
