I have a matrix A of dimension 129*135. I want to make it 135*135 by adding some NaN values. How is it possible in a simple way?

a(end+1:135,:)=nan

The same thing
a=rand(129,135,33);
a(end+1:135,:,:)=nan

Hi
There are a number of ways you can do this. At the command prompt type:
help vertcat
and
help nan
This will get you started. Matlab's very powerful at indexing etc. So reading through the basic tuturials and examples will get you started quickly
