for i=1:40 variable L I want it to be named L1,L2...L40 according to the i value in the loop.is it possible to do so?

Here is a sample code which does what you want. Try it.
for i=1:5
x=num2str(i); % Converts number to string
x1=strcat('L',x); % Concatenates your prefix to the varying number
x1 % I guess, this is the variable you want
end
Hope it helped.

I think it's more likely to be the faq 4.6 as Walter suggested, otherwise the OP should be more specific.

Please see the FAQ
Why do you "need" to do this? There is almost always a better way.

Sounds like a reason to use dynamic field names on a structure, and to use the '-struct' option of save()
