Split a vector

Hi,

I have a question regarding vectors: I have a vector of size n and I want to split the vector by a matlab function so that I get elements 1-10, 2-11, 3-12....

Is there any built-in-function?

Thanks!

Split to one matrix:

n = 20;
% create vector a
a = 1:n;
m = cell2mat(arrayfun(@(x)a(x:x+9)',1:n-9,'UniformOutput',false));

Splitting to one matrix you can also perform with this code:

a = rand(20,1)
n = length(a);
[x y] = meshgrid(0:n-10,1:10);
a(x+y)

Split to vectors:

n = 20;
% create vector a
a = 1:n;

for k=1:n-9
    eval(['vec' num2str(k) ' = a(k:k+9);'])
end

Do you know the BUFFER command?

I think I did not describe my problem exactly. My aim is to vectorize for example this code:

x=10;
vec=1:1000; 
result=[];
for i=1:end-x
   result[i]=vec(i:i+x);
end;

In my opinion I've given the solutions in the post above :)

x=10;

vec=1:1000;

[i1 i2] = meshgrid(0:x-1,1:length(vec)-x+1);

result = vec(i1+i2)
