how to resize a matrix?

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?

Answer 1

a=rand(129,135) % Example
a(end+1:135,:)=nan

if the matrix is three dimensional say 129*135*33 and i want to make it 135*135*33 by adding nan how can i do it?

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
