Hi,
c=[5 7 1 9 10]; I want to create a cell from this vector as:
d={[5 7 1] [7 1 9] [1 9 10]};
Thanks in advance.

c=[5 7 1 9 10];
m=3;
out=arrayfun(@(x) c(x:x+m-1),1:numel(c)-m+1,'un',0)

hi, error message:
??? Attempted to access r(1); index out of bounds because numel(r)=0.
Error in ==> hankel at 26 elseif c(nc) ~= r(1)

This error is shown when the second input to hanker is empty:
hankel(1:3,[])
In the code above this occurs because,
  • 3:numel(c) is empty, because,
  • numel(c) is less then 3, so,
check the contents of c !
