x = unique(wavelengtha_5(:));

They are already in the same variable, but if you mean how to reshape for example the variable x

out=x(:)

Hi. but it doesnt add up in running sequence.

[Azzi Abdelmalek]

What do you mean?

[hithere]

for example the variables is like this:

1   2   6
3   4   10
5   8   12
7   11  13
9   14  15

if they were in different variable, a union function will be

1
2
3
4
5
6
7
8
.
.
.
15

in ascending order and eliminating duplicates.

So im think how to have the same effect in this scenario.
