Hi,

is there a better way to create a simple array of acsending numbers than:

foo = reshape(1:9,3,3)
foo = 3×3
     1     4     7
     2     5     8
     3     6     9

Thanks

No, that is the best available -- unless you want to count

foo = reshape(1:9,3,[])    %3 rows, as many colums as needed.
foo = 3×3
     1     4     7
     2     5     8
     3     6     9

If you have the Computer Communications Toolbox, you can use

foo = buffer(1:9, 3)    %3 rows
foo = 3×3
     1     4     7
     2     5     8
     3     6     9
