example1=[25 20 30 40 50 60 70 80 90];
ex_perm = reshape((perms(example1))', 1,size(example1,2),[]);
I want [example1; ex_perm] format.
Means 1*9*362881 Matrix.

That is not combining two matrices. The code you show looks like it would work. An easier way of doing that would be
ex_perm = permute(perms(example1), [3 2 1]);

Sir, I need to combine it urgently. please help me...because my initial guess is works fine than other permutations.

Ah, I did not notice that you wanted another copy of example1 in there. Note that the original form of example1 will already be included in the list, so only do this if you do not mind having a duplicate entry.
One way:
permute([example1; perms(example1)], [3 2 1])
Another:
ex_perm = permute(perms(example1), [3 2 1]);
result = cat(3, example1, ex_perm);
